Quis Custodiet Ipsos Custodes?

I am finding it hard to express verbally (or in type) just how excited I am for the new Watchmen movie coming out this week. This story raises all kinds of interesting questions about morality, God, and human nature. I don't want to spoil anything for those of you who haven't read the comic, but if the ending is anything like it is in the book, you will leave the theater unsure of what would have been the right thing to do, and those are some of the best stories I ever read/seen. For now, I'll leave you with this logical argument:

1. Rorschach is morally committed to the proposition "murder is wrong".
2. If something is wrong, then it should be punished.
3. Rorschach has committed murder in the past.
:. Rorschach should turn himself in.
