Not any worse than Protestantism. Both perverted Christ’s Body by adding and subtracting to the beliefs we hold. This was initially done by people that yes you could say were under “demonic” “evil” impulses because of their pride and lack of humility. Satan can only work with us, he can not force us to sin. And only God can allow Satan to do anything. So yes, I would agree that the roots of other religions that exist since Christ time, that developed from the Church are evil in that sense. But I would lump your religion right in there since you do not claim to be Catholic, yet somehow are Christian.
That does not mean that I think you are any Muslim is destined for Hell. Only God knows how much a person is rejecting Truth, and how much he truly is misled.
