However, it could be argued that there are many types of personalities and they have different motives or they work without motive.

For example demons or perverted people harass others for no reason. It is there nature to do so.

When God Ram said demon Marich,'It is my duty to protect the religion and virtuous persons and sages. It is my religion to give protection to pious deeds and rituals. You should not disrupt such people and such pious activities..'

Marich replied, 'It my duty and religion to destroy pious people and activities. It my religion to fight against religion. You go ahead with your religion of protecting pious people, I will continue with my religion to harass and kill them Who are you to tell me about my religion?' Eventually Marich was killed by Ram.
