Should they have kept him chained up in the basement?
Have you ever heard of therapy? Millions of shrinks of all kinds, counsellors, family thrapists, grief counselors, etc etc. Even a frigging life coach. Something. You think there is nothing family can do except your chain up sugestion. You extremist simpleton.
You look after family. Yeah maybe you do keep am eye on him if hes really nuts. At least dont let him be out in the world by himself.
Use your frigging brain.
