At first I thought it said, "Even snitches don't deserve stitches."
"Snitches don't even deserve stitches" is SO much better than my initial misread! The former is over-earnest and has the benefit of compassion. The second sounds shallow, resentful and even whiny, which of course fits perfectly with the character.
Also big ups to Sunny's heavy-lidded, cynical agreement and "son of a FISH!"
