became outlaw by accident, any way i can reset my rank to 0?

Talk to villagers, gift villagers stuff, excuse to villagers after you hit them

its like 1500, there is no way to reset it?

Do you believe that this is an error? To reach such an score you need to murder approx 10 villagers in front of the whole village.

Resetting such a score requires complete genocide, or you need to wait until they sent a few waves of bounty hunters, as that increases your rep again.
