Forgiveness and Revenge, Dangerous words: part two

What is forgiveness?
Well Christianity and Islam both preach forgiveness and also have the belief that God can forgive, has the power to forgive, and forgive anything. I remember studying the Abrahamic religions in College and he hammered out the difference with these two, and what Judaism, the root Abrahamic religion, has to say about forgiveness. And it was that a sin is a sin. There was no wiping a sin clean through penance, or confession or anything. God could not forgive Cain for what he did to Abel, because it was not God's place. It was Abel's place, and since Abel was dead, Abel was also unable to forgive Cain.
If we were to look at the Marathon bombings from this perspective, Suspect #2 could conceivably receive forgiveness from those that were still alive for what he did to them, though there is no reason why they should have to forgive. But even if they did, the three that died, are dead and therefore cannot grant forgiveness. And nobody can really forgive in their place.
This type of thinking was difficult to wrap my head around at first, because I grew up in a somewhat Christian/Buddhist culture. What I mean is that I watched a bunch of movies with themes from these religions and heard a bunch of people who were part of these religions speak about forgiveness.

More and more, I do not believe in forgiveness. I believe in compassion, sympathy, and love, but not forgiveness. Some people say forgive and forget. Some people say forgive, but never forget. Forgiveness takes a lot of energy and a lot of people use it as a way to move forward and heal.
I believe in moving forward and healing. But, for instance, you would not forgive a disease or a hurricane. You would not forgive a car accident.

Now I am not with the people that are saying we should hang this guy public execution style Downtown either. Why? That just gives him more power. It would give his memory more power, and his message of hate more power.

I don't believe in Forgiveness. But I don't believe in hate or revenge either. Not to say that I have never had a hateful or vengeful thought. I have. But I try not to. And when I have them I try to think of something else. Because those thoughts are not useful, helpful, or beneficial to me.
We should use all our thoughts to preserve the memories of those that died and those that still need help recovering. All of our energy should go into moving forward and making ourselves stronger.
If you sympathize with the perpetrators, or knew them, then preserve the memory of what they were before they turned into what they turned into. And if you hate them, and curse them and wish them to hell... know that in order to do the things they did, they were already in hell, and full of curses and hate. So don't go down that path. It looks like it only took a little over a year to go from "normal" to follow that path to a point where they were capable of putting bombs in a crowd.

What should this suspect who is still alive do? Not seek forgiveness. But if he were to "see the light" as it were. To try and work from inside your cell in jail or on death row, to prevent others from following your path of hate.
Whatever ever their reasons, there were so many other things they could have done to send a message, so many more powerful and less destructive and evil things they could have chosen besides a bombing.
