You know shithead can turn into good person if they learn how weak they are and how strong human
Very rare those survive from torture and human let them go the bad trauma will help yukkuri they never go in human place again
No, once a shithead, always a shithead. Yeah scum can be redeem and learn how futile it is to oppose human, but shithead always consider themselves league above human no matter what kind of situation they're in. If they experience the harshness reality, they will immediately think that this is weird, that shit human just do some kind of tricks because there is no way a greatest/easiest, yukkuri among yukkuri can be defeated in a fair fight bla bla. Don't trust me? Just search shithead in this site and watch.
