Don't ever make friends with a Psychopath

I feel sorry for hateful, vindictive people with psychotic anger issues.

I am even sorrier when I meet one of them,
get sucked into their deception,
consider them a friend,
defend them to others,

and then find out their true colors when they take advantage
of my friendship, lie to me, and then have a scary psychotic outburst
and threaten me for daring to criticize their behaviour.
