This quote portrays a person as someone dangerous and morally questionable. It describes him as not a healthy or stable individual, emphasizing disturbing behaviors like using a shock collar on a husband and getting high from frog slime. The mention of possibly having killed people suggests a dark, violent nature and a lack of empathy or remorse.
The quote also hints at a paradox, implying that although this person engages in heinous acts, he still holds some beliefs or convictions. The author may be highlighting the contrast between his brutal actions and the idea that he genuinely believes in something, possibly making him more unsettling and complex as a character.
