MCU: 10 Worst Things The Avengers Have Done
1. Clint Turned Into Ronin
There was no one in the universe that wasn't affected when Thanos snapped his fingers. Those lucky enough to survive would have almost certainly lost someone close to them. Some may have lost more than one person, and some lost everyone they cared about.
Clint Barton was one of the latter, losing his wife and three children to Thanos. Grief affects everyone in different ways, and with his entire family gone, the man formerly known as Hawkeye began a crusade of sorts, seemingly targeting bad people who survived the snap.
In Endgame, Rhodey reported that Clint had slaughtered an entire gang of cartel members, and when Nat caught up to him in Tokyo, he was cutting his way through the Yakuza. While the Avenger appeared to be choosing his targets rather than killing without discrimination, he still became a mass murderer.
Within the confines of the MCU, this is really no different to what Frank Castle did after his family was taken from him. While we haven't had a chance to see what happens to Hawkeye after Endgame, with a kill count this high, surely he will be labelled a monster and a wanted man much like the Punisher was after his killing spree?
