Oh my Lord,  why did he stab the other?  Didn't he say anything about the reason behind it??  It's unfathomable for me...  I feel really sorry for you.    I have been a child in very violent home,  which left many scars as a lot g term (18 year)  constant  violence and abuse,  but holy crap...  Seeing THAT,  someone stabbing someone must of been terrible.  I can't even imagine how you must have felt...
