I have a question regarding Islam?

God is supposed to be all powerful, all knowing, ever existing, perfect, and righteous. I'm more merciful than God because I wouldn't starve anyone to death and I wouldn't put anyone in fire forever, I would save everyone if I were God. I would save everything and stop the nonsense crap in existence. Everyone would be one loving family with great pets and paradise for everyone. I would protect all people and things. I would fix everything that God messed up.
