I have power over other adults... is it normal that I see them as children?

Bullshit. Stupid ass edgelord, probably still in high school.

Don't let that autistic desire to be like your beloved fictional supervillains and/or tumblrina crush on serial killers overtake you. Focus on your own life, why you're so unfulfilled as to define yourself by these delusions, and eventually you won't have time to sink into these childish fantasies anymore.
