I don't think that's what the OP meant though. I read that as the OP did not want to get into a situation of trying to give advice to a known/admitted guilty party.

The irony in my eyes is that everything OP said applies to someone who is genuinely guilty. Furthermore, for all we know, all defendants could be genuinely guilty (icluding OP), because of the incomplete information we have of the world. That's the nature of the knowledge we have of others, and justice process in general. OP pointed this out, in not so many words, but then finished by saying [paraphrasing] "don't seek my advice if you're really guilty". I enjoy the irony in that, and I empathize with the dissonance.
