trippin' hate

On my way home today I was tripping down memory lane when my thoughts were suddenly invaded by a certain person who I was once good friends with. The total feelings of utter hatred and contempt rose in my chest and surprised me. I had forgiven him for the sin of being alive more then 10 years ago.
It led me to the question of can you hate someone who you have forgiven? If you still hate him maybe you didn't really forgive him. So I called my sister, who is one of the few people who would understand that question without needing any explanation.
She felt that you can hate someone who you have already forgiven and it is still a full forgiveness. Her reasoning was that while you have forgiven a specific act that the person has done, the person isn't going to change and what you hate is the way this person behaves, which will continue with or without your forgiveness.

I'm not sure I agree with that. When I forgave him, it was before Yom Kippur and I said "I forgive that jerk, but I still wish he fell off a roof and was still alive to feel himself get rolled over by a truck." In any case hatred is very powerful. As it is said, "Fear leads to anger, anger leads to hate and hate leads to the dark side." In the newer movie (which I haven't seen) Yoda says that hate leads to suffering, but in the original he stated correctly. Hate leads to the dark side.

Another question I was thinking about is why this person invaded my thoughts. Does that mean that an event had occurred with him, so his presence was stronger in the universe or was it just a random occurrence. A lot of people from the past came to me while I was driving and for the most part it was a very pleasant experience.
