we should rather eliminate it.

Unfortunately, that will be an impossibility cos it's ingrained in human nature. Yorubas have a saying to corroborate this fact...

Omo ale lo ma n rinu ti kii bi, omo ale naa si ni won ma mbe ti kii gba. meaning...

"It is a bastard who never gets angry at all, and it is equally a bastard who doesn't accept plea when angered"
