We are apparently still stuck in this stupid zero-sum game mindset.
If you have a Levaya with more then 10 people for CW it is a terrible shameful event. I don't care if it is a Mitzva and you were his chavrusa for 30 years, if you dare go to the guy's funeral, you are perpetuating the cycle of abuse and will be held responsible for the next story of abuse that breaks.
Once at the levaya, everyone should either shut their mouths and not say a single word of hespedim because obviously any kind word you may say in front of the bereaved family is another act of abuse and molestation against the 10,000 victims of the monster himself and if you say a single nice word about Chaim Walder (even if it is the absolute truth) his victims will kill themselves and the blood will be on your hands.
Forget about the whole Shiva business, Let the family rot!
Either the family knew and helped cover it up or they are just stupid and oblivious. We just can't care about people like that, not when we can be celebrating with all the would be victims that were saved by the monsters death. In fact, we should throw a massive kiddush right under the family's window and blast happy music and have free L'chaims just to show how much we support abuse victims.
Anyone who does anything else or dares frown or show any emotion other then absolute bliss at the mention of Walders passing is to be brought up on charges of sexual abuse and/or murder in both this world and the next!
