What matters is wether or not this guy has the right to do with his property what he wants to. If he doesn't like it simply because it is ugly, smelly, or messy he should have the right to get rid of it because it is humpy. We are talking about a piece of property, no different than a pair of shoes, a tv, or a frozen pizza.
He should be able to dispose of 'it', or treat 'it' any way he pleases because it's his property.
Well fortunately people with a better ethical sense towards animals have in places animal cruelty laws. So no people can't do anything they please with their 'property'.
