Personality factors shape the nature of anime characters and reflect their multifaceted tendencies. These also reveal their dispositions and temperaments, whether they are forgiving or vindictive. First, there are the vindictive anime characters who like to hold grudges against others. These characters usually have a crass personality, which is why they are so vengeful. Some of them even hold grudges for the entire series, settling for nothing but ruthless revenge.
Second, there are forgiving characters that do not like to hold grudges against others. Even if it's an action that looks unforgivable from the viewer's eyes, they just don't want to spread hatred for the sake of mental satisfaction. Instead, they forgive and spread a message that is far better than hurting others.
