Is it normal to love gore?
Liking gore in horror movies, games, or special-effects makeup is normal; people vary a lot in what they enjoy watching. Enjoying real people’s suffering or wanting to cause harm is a different matter, and worth taking seriously.
If you mean fictional gore, you’re in plenty of company. Some people enjoy the shock, suspense, practical effects, or over-the-top spectacle; others would rather watch literally anything else. Neither reaction is unusual.
If you mean real injuries or people suffering, that’s a different line. Being curious doesn’t automatically mean anything is wrong with you, but if you’re seeking out real suffering for pleasure, feeling distressed by your reactions, or worried you might hurt someone, talk it through with someone you trust or a mental health professional.
