Doesn't God Hold People Accountable for How they mistreat animals?

Because we can't know for certain I think it would be irresponsible to not holdpeople accountable for what they do in THIS life. Plus, not everyone is religious so it would be a little weird to just get rid of our laws (and being humane to animals IS a law) on the idea tht God will sort it all out in the afterlife. With that logic we should just let murderers and rapists roam the streets. It's not so much about punishing people for what they do. It's about the quailty of life for the victims. If there is a God I would think that He would judge people most harshly for allowing injustices to happen right under our noses and turning a blind eye.
