I think that The Walking Dead has used up the morality questions such as killing Walkers or harming bystandards for the sake of the group. But what about what Michonne did.
Yes the Gov tried to kill her but she got away. She could have just told Rick and company where Glenn and Maggie was and left it as that. But she decided to run a special side mission to attack the Gov. Thanks to that move, the Gov is down right livid with grief and vengence on the mind. Sure the Gov was going to be a threat to the prison but now they are his mortal enemies.
Not only did she put Rick and company in danger, what if shedid kill the Gov? Would the town and the pseudo-peace there survive? In killing the Gov, she might have doomed all those ppl to death and destruction.
So, was Michonne correct in trying to kill the Gov?
