5A. שו"ע 345:5 – Any person who is poreish from darkei tzibbur, want to be considered like rest of the non-Jews, no aninus, no aveilus, wear white clothes and have simcha when they die. Presumably, these are ppl who don’t want to have anything to do w/ Judaism.
B. רא"ש שו"ת 17:9 – Does one sit shiva for a meshumad? Says psak in Maseches Smachos is no.
C. Mordechai MK – Tell story of R’ Gershom who sat shiva for his son who went off the derech.
*But does that mean when he died or when he went off the derech?
1. Hagahos Ashri – He sat shiva once the child went off the derech 14 days.
