You said,"If they had called the police they wouldn't be dead."
That is a indefensible statement as there is no way for you to know that.
You said: " Obviously this guy didn't have very good people skills... Maybe he should have called police, and let them handle it... or he should have took some more "self-defense classes..."
That is implying that the victims were at fault.
As for you attacking members of this forum... that is evident.
