Sass: Stop generalising - it does niether you, nor the cause of Christ, any favours.
Baal worship was a tiny part of what you call paganism.
Human sacrifice, archaeologically speaking, an even tinier.
Human sacrifice had died out, in the main, at least 2500 years before Christ was Incarnate.
It persisted in uthe insignificant nation states between the Fertile crescent and the Nile Valley untill the Assyrians wiped it out.
If there was Iron age human sacrifice in Europe from c500BC onwards (and modern historians doubt the Roman claims as propaganda), it was wiped out before the end of thw first century AD - and the advance of Christianity had barely touched Europe by then.
Whether you accept modern neo-paganism or not (and, as a believer, I accept only One way to God - Christ Jesus, God Invcarnate). it has little or nothing in common with satanism, clairvoyants, seances, or drivel like that - most of which was actually invented, not by pagans, but by ex-Christians, whomnot I, but a far greater judge, will judge in due course.
Whatever happens is up to Him.
