False correlation. A limited fictional invention that pagans lost in spiritual darkness sacrificed humans to simply does not correlate with the non-fictional one true Creator God who loves humanity to the extent he offered Himself as a sacrificial atonement.
People formed false religious systems based on an erroneous worldview and epistemology early on just as they continue to do today though the knowledge of God was present from the very beginning and remains so today.
A unique separate monotheistic account refuting subsequent pagan cosmology and creation with Christianity's core beliefs was present (e.g. God would take on flesh, die and rise again for humanity's atonement) among Abraham’s Horite people before Abraham that asserted its existence from the origin of humanity.
You need to pay more attention to history. The biblical assessment shows no interest in granting a sympathetic hearing to fictional false gods. These fabrications are fictional and worthless. Their existence, if it extends beyond the idols that are made by human hands, is demonic.
This jealousy they inspire in God for His people (which provides a stumbling block to at least one atheist here) is a godly jealously. For example, Paul's jealousy for the church was commendable. He wrote, "I am jealous for you with a godly jealousy. I promised you to one husband, to Christ, so that I might present you as a pure virgin to him" (2 Cor. 11:2). Likewise, there is nothing wrong with a husband having appropriate jealousy over his wife (or vice versa), since she belongs to him (cf. Num. 5:14) and he to her.
The foolishness of idol worship and the horrid demands of fictional pantheons, up to and including human sacrifices) does not compare to the true God offering a relationship of love and joy in a environment of forgiveness which He Himself provided sacrificially.
Of course people being led astray by the devil from God into deception, wickedness, and ultimately perdition arouses intense emotion from a holy loving God.
Odin Denial is a temporary delusional state which dissipates upon the death of the physical body at which point the Odin Rejector's soul enters spiritual dimensions beyond this material universe for judgment, without the benefit of atonement, before Odin almighty.
