Satanism?.....?

a devil worshiper might ask you why you would believe in a "god" that is willing to wipe out all people on earth with flood, or allow m murder, or allow children to be d and brutally tortured..yet stand by and do nothing...a satanist might say that god has the control to intervene in all evil yet stands by idol. why would anyone worship this being?... satan is just a tempter..seems pale compared to the evils that god has done and allows...
