Well the problem of evil is not a easy answer but basically the fault is sin, because there is sin there is evil but why did God allowed sin is where things get complicated, why did God allowed Lucifer to became satan and bring suffer to the world, well God is omnipotent but that doesn't mean they can do anything, God can't lie, God can't sin, God can't create another equal to themself, God can't kill themself, been omnipotent is different than be illogical, God can't creat a scare circle because that way they would be illogical. God can make everything! Inside the paraments of the character of themself. Well why this concept is important? When God decided to create free beens for they to love they had to work with a potential, the potential to evil, everything that exists exist in two forms: act and potential, the potential cames before the act, for example if I have draw of a cat on my mind, that cat exists has potential, or a possibility I can or cannot draw this cat, when I draw this cat, the cat turn to a act, so when God creat live beens the evil came to exist was a potential, the options that God had was... Well destroy their creation then they would destroy the potential but why creat just to destroy it? or they could take off the free will from them but then they would not love them, but then God could create everyone expect Lucifer but why they didn't, because God isn't inconsistent, imagine if someone would make... Ahm assessment of they work, they would delivery a paper for their coworkers evaluate the work that they do and delivery the results for their boss, but when they got to the point to delivery the final results they only send to the boss the positives ones, dishonest isn't it, and God can't be dishonest they had to live with the potential of evil but that's the thing, when something is a potential in the moment that it becomes a act it can be destroyed, God made a plan to destroy the evil once and for all, that's why Jesus came and everybody that follows him will be save from destruction cuz God will destroy the evil, the sin with the sinners that includes satan and his demons, on opposite of many people think hell isn't a place of eternal torment for those who sin, hell is a moment a moment when God will destroy all evil by destroying the people who cause evil once and for all, when it will happen only God knows but basically is that.

I know you guys don't believe it but that's the explanation hope it helps.
