Yeah but the difference between Krudge and Klaa was big. Krudge wanted to obtain a planet destroying super weapon that supposedly threatened the Klingon Empire. If he was successful he would've removed that threat and obtained a powerful weapon.
Klaa was just bored and decided to start some shit for no reason. Big difference. I could see Krudge's latitude being supported. Heck it was, by the Klingon ambassador in STIV. There was a threat and a purpose to it. Klaa? Heck even drunken Korrd thought it was stupid.
