I feel sad for mizuno yea he did bad things, but imagine getting compare like constantly and put down by his mother. It wasn't his fault his brother died. Yea he was being childish at the time, but who isn't childish nowadays? He was confuse and it seem like he was developing anxiety and depression. Haruka thankfully showed him the right path. In the end he wasn't a bad guy. The bad guys were the ones who standby and watch him tear himself apart, and the blackmail boys.
