Blaming God for the evil of the world is just an excuse to be angry with God. Those who are angry with God don't care about the evil in the world; they want to be allowed to do it without judgment, and even expect endorsement.
Christ healed people and did many other miracles, and the religious leaders accused Him of doing His miracles by the power of the devil. Those who hate Christ and who hate Christians will always lie, claiming the opposite of what is true.
Christ offered the suffering and wicked world mercy when they repented, heaven when they trusted in Him, peace, joy, and all the fruit of the Spirit, and all they had to do was trust in Him to change them into a new creation.
Stubborn mankind wants its own way even if it ruins them, as long as it makes them feel in charge and powerful in the moment.
Proverbs 28:26 "One who trusts in his own heart is a fool, but one who walks wisely will flee to safety."
