If you’re talking about fears, then I would have to say losing someone I love. I have Thanatophobia. A fear of losing someone you love. It scares me just to think about someone I see everyday, gets killed and they are gone.
Honestly, I don’t think people deserve to be terrifyingly killed. I would just let them die in prison because of aging. Even if they did the worst of the worst, it still doesn’t matter. Technically, it’s based on where you live.
