I Believe In Accountability
If you have done harm to someone, can you say "But I didn't mean to!", or "But that's my personality, I can't help it!"? I don't think that you can shirk responsibility for your action (and undue inaction) that way. You are accountable for what you do, and in many respects you are accountable for who you are. Hard luck sometimes, but there is a bright side to that: if you achieve something good by sheer luck, that too will be credited to your account.
