I in no way deny that our actions to humans, animals, and the environment would affect how we would be rewarded/punished. But, if we are to be judged on our actions towards creation, then we would definitely be judged on our actions towards the creator. God gave humans rights, animals rights, and the environment rights, all of which we must do our best to fulfill, so it's only natural we fulfill God's rights as well. So I do believe beliefs are important, more so than actions, as our actions primarily relate to the creation, while our beliefs relate to the creator, who is superior.
