People blame God for evil, because they lack of trust and faith in Him. When God allows certain bad event to happen in our life sometimes these are part of His bigger plan which we cant see with our little eyes or finite brain. Think about the Tsunami that take thousands of life can people blame God for that. Yes, maybe some might and some might not but certainly that was part of His bigger plan for something big.
No, God does not tempt us with evil, it is sometime our weak nature that makes us playing with fire, and ended up getting ourself burnt.
No, God does not tempt sinful people with evil, these sinful people are already living in their own nature of sin so how can God tempt sinful people with evil.
God allow people to sin so that through it, they can realised and come back to our senses how much all the more we need to depend on Him and by demonstration our love for Him we should try to stay clear from sin by relying on His strength then on our own.
He allow evil to exist so that through it, it can show how mighty and powerful is our God, even before evil can do anything they have to seek God permission (Job is a good example and the temptation of Jesus Chris is also another good example, all this happen because God gave the permission for evil to do so)
