Satan is the one who wants evil. He hates God, he hates you, and he wants you to suffer forever in Hell with him.
God & Satan[]
Some think that he is like God, but the opposite (evil). This is not true at all, Satan fighting God would be like a mosquito not being crushed by a plant falling on it, and even farther beyond that. God is infinitaly more powerful than Satan, so we should have absolutely nothing to fear if we are on God's side rather than Satan.
Satan doesn't make you sin[]
Satan can't make you sin. He can go no farther than tempt you, it is totally up to you whether you sin or not.
