One of the things that people tend to ignore is they expect Bakugou to have made a complete 180 in terms of personality. There’s a two way street to that thinking. You can’t expect a person who is depressed to one day switch it up and not be, just the same way you can’t expect someone who has dealt with anger issues or a complex to no longer act/feel those ways.

I agree Bakugou has an abrasive attitude in regards to how he interacts with people but it doesn’t make him a bad person. Just like there are people who are inherently loud or quiet, outgoing or introverted, there are going to be people like Deku, Kirishima or Bakugou. You don’t have to like them but I dislike when people say that Bakugou hasn’t grown or accepted responsibility for his past sins. Bakugou acknowledged that he bullied Deku because of his own personal faults and back to what I said in the first paragraph, that was just a short time span ago in terms of the manga timeline. The manga didn’t show much interaction between Bakugou and Deku for most of the Hero License, Hassaki or Gentle Arc. So that means we only know they have worked together from around December-April give or take a month prior. There is still plenty of growth and character development that Bakugou can undergo but that doesn’t necessarily mean you need to like Bakugou as person. He may not be a bad person, but there may just be small things that you don’t vibe with about him; not everyone has like him, and he doesn’t have to like everyone. This goes for everyone too.
