I fully agree with you - there are consequences for the person who committed the act. Hopefully they are affected by what they did. And that yeah, they aren't only what they did but so too, something that they did may colour everything else and who they were and it may change the way you perceive that person. Yes they have to carry that - it's kinda part of the consequences of the act.

I actually think there can be redemption but not necessarily in the way perhaps you do.
