thread not about redemption or forgiveness, it's about if he's a criminal. the answer to which is yes. he commited crimes, so he's a criminal.
so killing those samurai was ok?
not about forgiveness. those samurai are people too, and he invaded their country and their military base. he attacked an international summit of world leaders. he also attacked bee, another nations jin. he also joined 2 criminal organizations.
he killed for himself. when shinobi do it, it's for the country. usually this only happens to country's they are at war with. shinobi don't go around killing random people.
he was still the elected hokage, at least by the daimyo. samurai are people too. he joined 2 criminal organizations. attacked another villages jin. helped them complete the juubi. and invaded a foreign land to attack a summit of country leaders. he's a criminal.
