I understand the frustration. I'm not disagreeing with anyone's "fun anecdotes", even if they don't fit in this context. All I have said is either do something productive about it, or put up with the fact that bad things occasionally happen.
My suggestion: Learn from it. Improve. Have fun. C'est la vie and Hakuna Matata.
Alternatively, mope about it and complain that you didn't know and how life is so unfair.

Have a little circlejerk and all feel sad together.
You're not wrong. But why not cheer up, see the positive side, start over? There's nothing you can do about it now, the character is gone. Dead. He's passed on. He has ceased to be. He has expired and gone to meet his maker. He's a stiff. Bereft of life, he rests in peace. His metabolic processes are now history. He's off the twig. Kicked the bucket. Shuffled off his mortal coil. Run down the curtain and joined the bleeding choir invisible. This is an EX-CHARACTER.
Or just do whatever. I don't care anymore. All I did was weigh in with my opinion, now I've somehow been dragged right into the middle of it. o_O I'm going home.
