Calling an evil ideology monstrous because it’s the truth. Monstrous is “inhumanly or outrageously evil or wrong.” Monster is several. “A threatening force,”, “ one who deviates from acceptable behavior,”, “something monstrous.”

By definition Nazis are monsters. Doesn’t mean we, as humans, aren’t capable of monstrous things because evil lives and grows among us every single day. It does mean we need to accept the fact that this entire ideology and their actions were monstrous.

Playing definition games is pedantic. Nazis are monsters and should be defined as such. Calling them what they are is preferred.
