I'm not saying Hitler did nothing wrong, but the relic should be fine, right? He literally have several relic of gods of destruction/war (Seth), poison/plague (that Mesopotamia one), cult/harem, and have underlings who control 72 demons, including one that excell in brainwashing.
From the present showing of power, the Hitler relic seem like another army summoning relic, just with gun. And silent.
