With power comes responsibility

In Ramayana, we also see the sixth avatar of Vishnu, who was Parasurama. Vishnu took the Avatar as Parasurama to control the dominance of Kshatriyas. Parasurama even though born as a Brahmin, had great power by god's grace. After he taught a lesson to the Kings and the Kshatriya race, he did not stop. He continued destroying them. He forgot his true responsibility. Only after Rama defeated him in a combat, Parasurama realized his folly.
