well I'm aware that as Christians we have to be grateful and forgivable in our lives. However in case of sexual abuse there is exception sometimes. Abuse is so morally and psychologically complex issue that is on some other level needing to be viewed not just and only as religious matter.
We survivors have in first place to do huge amount of work related to our own well being and recovery from so devastating thing like abuse. To be able to forgive our abuser - work that should be done to understand overall picture is even greater and task more complicated. Please try to put more energy in understanding your abuser, his actions and all about devastating scars that abuse left on you. Be aware that there are many situations when it is not healthy and not possible to forgive.
And nobody would go to hell because of that.
Goal of confrontation to perpetrator doesn't have to be to send him to jail (even institutional dealing with some of them should be priority; many abusers are repeating abuse and we have to fight so terrible crime). We as Christians have to think always and in first place on safety of innocent children and people - this includes also closest abuser's family members who also could be abused and in great pain.
Some other reasons for confrontation perpetrator are:
"Some survivors have requested money to pay for their therapy as a means of restitution for the abuse. Others have used the letter to establish boundaries with the abuser. This may mean the abuser is told not call or contact the survivor without the survivor's request. The survivor may insist on an apology or have the abuser confirm to other family members that the abuse did indeed take place."
Thirdly we have to be responsible and protective to ourselves. Nobody has rights to use us to his own selfish wishes and needs. Our responsibility and compassion to ourselves as innocent victims has to lead us to some actions. Passivity is in any case totally wrong and irresponsible to victims (ourselves), put it in religious colors or not that is the fact. So please think more on all this and see what suites you the best.
Here is one thread about confrontating abuser with aim to find some details about abuse, nevertheless maybe reading it could give you broader perspective on all this: http://www.malesurvivor.org/board/ubbthreads.php?ubb=showflat&Number=394707&page=1
And here is one book that some brother survivor recommended it, it is about how forgiveness often proves very destructive for victims of parental abuse: http://www.amazon.com/The-Body-Never-Lie...4552&sr=8-1
I hope that this will be helpfull to you.
