Hypocrisy is fine. I’m totally okay with a commited thief shouting from the rooftops, “It’s shitty to steal stuff!”
A) He’s not wrong.
B) He adds to the social pressure against being a thief.
I don’t think implicit in “being a thief is shitty” is “I personally am not shitty.” He could easily be saying, “It’s shitty to be a thief, and I’m a shitty person.”
