What do you call a person that will return a person actions and what they did to them back even if it means behaving bad or a bit crazy even when the person that acted disrespectful to them gotten better

Answer 1

A person who responds to another's disrespect or wrongdoing by returning the same behavior, even when the original offender has changed for the better, might be described as "vindictive" or "revenge-seeking." They might also be viewed as having a "tit-for-tat" mentality, where they believe in responding in kind, regardless of the current context. If their actions are particularly excessive or irrational, they could be labeled as "petty" or "spiteful." In some cases, such behavior may stem from a desire for retribution or a difficulty in letting go of past grievances.
