They will not forgive anything! The three most vengeful zodiac signs are named

Some people don't know how to forgive at all – they remember all the insults even after many years and wait for the right moment to take revenge. According to astrologers, this is related to the zodiac sign. Capricorns, Scorpios, and Aries prefer to take revenge rather than forgive.
Capricorn
Ambitious Capricorns, although they may seem sensitive and vulnerable, can gather all their will into a fist and take revenge on the offender who hurt their feelings. However, they will first analyze and calculate carefully. Capricorns will strike when the offender is not expecting it. In this case, they will not rely on fate but will think things through themselves.
Scorpio
Scorpios are the darkest, most dangerous, and most vindictive sign of the zodiac, so it's best not to get into a conflict with them. Natives of the sign can take revenge even for an innocent joke that others would not have paid attention to. Scorpios will find their enemy even years later and want to ruin his life. They will not "let go" of a person until they have enjoyed their revenge and are convinced that the offender is sorry for everything.
Aries
Aries quickly flare up in a conflict, but they also cool down quite quickly. However, if a person falls under the hot hand of a fire elemental, he or she will be in trouble. Aries are not the type to wait for a long time to take revenge. They try to strike immediately and painfully. If you had a conflict with the natives of the sign, it's better to wait out the storm until emotions subside. Then there is a chance that Aries will agree to a truce.
