Do you honestly think that we all deserve eternal torment? Think about someone you love. Why do you love them? Because you see the good in them, even if this good is merely a reflection of God. Imagine them suffering for all time simply because they did not understand God's message. Can you truly think that a good God would want that to happen and that he would stop it if he could? And if he is the creator of the universe, why couldn't he have stopped it from happening?
If we are saved through grace alone then everyone is saved because choosing to believe is an action (a 'work'). If we are saved through works, then there must be good people.
Because God has a plan for our salvation, he must want us to be saved, correct?
If he wants us to be saved, that means that he at least thinks we are worth saving.
That means that there must be good in us.
