Steve, I too am able to be very happy for the people who mistreated me, when they kick the bucket! It's their liberation from the bondage of flesh and ego (maybe the latter not totally). So I can legitimately rejoice at their Death.
I hope you read the post I just sent you above also. Although I laughed rereading this I hope you really did not mean it.
i believe that various circumstances come in people's lives that test their kindness and truthfulness. Often we or they succumb to circumstances and follow the line of least resistance choosing the darkside. In this sense we are often unable to intuit spiritual or abusive tendencies until circumstances bring them to the fore.
