Bumaro is shown to be extremely devout to his religion, as he has dedicated his entire life in serving his god. He is determined to rebuild the broken god and exterminate the flesh plaguing humanity with whatever means necessary. He is ready to commit whatever crime necessary to achieve his goals thinking the ends will justify the means. Even though he and his church caused major troubles to groups such as the SCP Foundation, he is not ruthless as he somewhat values the lives innocent people.
