Rav Sternbuch (1:368):Question: A baal teshuva, when visiting his parents who have a television, damages it in order that the family members will not watch it. Is it permitted for him to damage so? Answer: The prohibition of watching television is very serious and it is an aspect of sexual immorality. That is because as the result of watching this impure device it increases his attraction to sexual sins. Therefore it is definitely necessary to stop a person from watching television in various ways. It is literally a psik reisha ( a direct cause of sinning) for someone who lives in a house with a television which degrades those who watch it. However there is a dispute between the Ketzos and the Nesivos (C.M. 3) whether the ability to force someone to do keep a mitzva is uniquely permitted to beis din or whether every single person is allowed to force others to keep mitzvos. According to the Ketzos it is only permitted for beis din while the Nesivos says that every person has a mitzva to prevent others from sinning.... Accordingly the Nesivos would permit in our case to carry out whatever activity is needed to stop television watching. In contrast the Ketzos says that only beis din has the power to decide and therefore the individual can not act on his own initiative to harm another’s property. However it would seem that those poskim who require permission from beis din are correct. We also see from the Yereim (#278) that coercing that might involve death is considered a knas which can not be done by the layman but requires mumchin (expert judges) in Israel. See also Minchas Chinuch (Parashas Bo). And even if the actual halacha was that each individual has to obligation to force mitzva observance, it would appear that we shouldn’t have a system of anarchy where one person can decide to harm to property of another. Therefore even if it were allowed – it is necessary to consult with a beis din before doing anything. That is because pragmatically there are times that this vigilante action against another’s property will cause the other person to be turned off by Judaism rather than making him more observant. Thus no one should take the property of others with the claim that they were only doing it for the sake of Heaven in order to stop him from sin. Furthermore it could be that the halacha only would permit taking another’s property when the sin is a monetary one. However in this case where the obligation is to prevent him from doing a sin, it is not relevant for an individual to force compliance by taking another’s property. However in our case property is not being taken to force him to behave. Rather the question is whether to destroy an impure device which causes spiritual harm and encourages transgressing severe sins. Thus it seems we are only destroying evil. Support for this view is found in Berachos (20a) which says there was the case of a certain pious individual who ripped off an immodest red garment from a woman that was worth 400 zuz. It seem from the gemora that such an action of stopping immorality is proper in a case of chilul haShem– even though it caused the pious person to have to repay the 400 zuz. So surely in the case of the television which causes much greater impurity. Similarly we see that Rachel stole her father’s idols to stop him from involvement with idolatry as Rashi (Bereishis 31:19) explained.
However despite these apparent proofs that an individual can act on his own initiative, I feel that every such action requires a consultation with a rav. We see clearly in the above gemora, that the pious person indicated that he should have been more patient and not have been so hasty to rip the garment. Also we see that Yaakov did not approve of this theft which Rachel kept concealed from him and in fact he cursed the person who stole the idols – and she died from the curse. (We see that sometimes a pious act causes much more spiritual harm then if no action were taken. And that instead of glorifying G‑d – the reverse happens as is known from many incidents.). It could also be that in our case it is not the appropriate time to stop them from watching television and an act that is premature can cause much harm. Thus even if the act itself is permitted it might be at the wrong time. Therefore the act can not be done in isolation of context and it is necessary to get permission with a wise person as to what is appropriate and to follow his words. It is also a good idea to speak with the parents and to try to explain to them that television causes much harm. And so even if they enjoy it for the moment – it will eventually cause severe harm to the entire family. In fact there is nothing comparable to its harmfulness. In conclusion, concerning damaging or destroying the television, even if he is willing to pay for it, it is best if he asks a posek before he does anything. One who acts according to the rabbis will always merit success.
קצות החושן (סימן ג ס"ק א): ואפילו לפי מ"ש הרמב"ן בחידושיו סוף ב"ב (קעה, ב ד"ה הא דאמר רבה) דגם למ"ד שעבודא לאו דאורייתא יורדין לנכסיו, טעמא דידיה לפי דהב"ד רשאין לכוף אותו בכל מילי דכפיה לקיים מצוותו ולהכי נמי יורדין לנכסיו משום כפיה והיינו כפייה דידיה לקיים המצוה בעל כרחו, וא"כ כיון דאינו אלא מתורת כפיה דהא הנכסים אינם משועבדים וא"כ מוכח דשליחותייהו דקמאי קא עבדינן.
נתיבות המשפט (ביאורים סימן ג ס"ק א ): גם מה שכתב [בסק"א] דאי שעבודא לאו דאורייתא והבית דין כופין בעי בי"ד [מומחין] דוקא לכפותו דהדיוטות לאו בני עישוי נינהו. נראה לפענ"ד דליתא, דכיון דדמי לעשה סוכה ואינו עושה דכופין אותו לקיים המצוה, כל אדם מצווה להפריש חבירו מאיסור אפילו מי שאינו בכלל בית דין, כדמוכח בב"ק כ"ח [ע"א] גבי נרצע שכלו ימיו, דיכול רבו להכותו כדי להפרישו מאיסור שפחה, ע"ש. ואי בעינן בגמר דין ג' והיינו לומר פלוני זכאי, יבואר אי"ה בסימן ה' [סק"ב].
