second-guesser
Perpetual decision questioner
A second-guesser is someone who questions decisions after they've been made, often suggesting what should have been done differently.
The term implies armchair criticism—it's easier to second-guess when you're not the one who had to decide under pressure: Every sports fan becomes a second-guesser on Monday morning.
