Subjective Morality?

[Belacqua]

[...] 

Have I done a moral thing?

No, you have not. Because deep down, you know what you did was wrong.

I think I wouldn't go along with this sentence as written. It comes across as meaning that because deep down the shoplifter knows he's wrong, therefore what he did was immoral. And that's troubling because it follows from there that if he didn't know it was bad, it wouldn't be immoral.

You failed to take ownership of your own actions, instead blaming them on a dead guy.

This seems more persuasive. I read it to mean that a person should take ownership of his actions and not evade responsibility. So it seems to me like a statement that a moral realist would make -- that taking responsibility in this way is axiomatic.
