Damn man... reading what happened to you i understand how you feel... what a tide of bad luck... its no wonder that youre having such evil thoughts... ive passed by a lot of bad things also, and they shaped me into the thing im now... i already had (and have yet) many dark end evil thoughts too... i used to indulge in such thoughts, as they are rather pleasurable... (oh yes... they are...:vader1 and today, when things arent alright, i still indulge in this thoughts... anyway... i treat them all as mere thoughts (cause its all what they are), and dont give much importance to them... i use them as a way to release the anger... but after have thought all evilness i wish, i leave them... even cause its a bit hard keep evil thoughts for long when the smoke goes to the head and you feel good... :rastasmoke:
Anyway... if youre passing through a hard time, if you want a new view of life, i advise to read this:

Carlos Castaneda's don Juan's Teachings

This teachings (combined with the weed) actually changed my life... my view of world... everything... before read it i was passing through a hard time (much like you), was a bit depressed (not much cause weed never let me down), hadnt any hope, any goals... then i did read, understood, and now im a new person... so i advise to everybody to read it... its a great well of wisdom.
There is also some quotes from there in this link:

So you can see how it is...
And at least... right now i havnt any dark thoughts to share... but when i remember some (i have plenty of them) i will post it here.

"Growing darkness taking dawn
I was me, but now hes gone"
