Gamzee is very passionate about his religion and extremely loyal to LE

Yeah he is, but I feel it’s more related to him being a Bard rather than him being a Rage Player? More specifically, to him being a Bard of Rage in conjunction, since LE has heavy Rage Connotations, as does the cult. You could make a case for it but like… I feel it’s more the fact it’s sort of the ‘true religion of Alternia’ where the Demon they’re worshipping actually exists and is a murderous unstoppable entity, rather than the fact they’re worshipping at all.
