I can't quite mesh the idea of an all-loving God with the idea of hell in my head, it just doesn't click.
I don't know if this would help, but the Catholic conception of Hell, at least from my understanding of it, is that Hell is not a place you are sent to. Hell is more a phenomenon, the result of rejecting God even when faced directly with him. The same way that refusing to eat means you go hungry, or rejecting heat means you remain cold, rejecting God (who in the Christian conception embodies all that is good, good and God being inseparable concepts) is in on of itself Hell. God is merciful, but also wishes to respect people's free will, even in such a choice.
Naturally the matter is a lot more complex than that, but maybe will help mesh the idea in your head. If you'd like to talk about it, I'm open to it, if you'd rather not touch the subject or just that I leave you alone, of course I won't try to pressure. Just responding since the topic was brought up anyway.
What musical artist would you most like to see perform live?
Depends on the definition of "live". If you mean the type of me going personally to the concert with like a stadium and stuff, I think I would go try to see one of those vocaloid projection thingies. I'm not a big fan of concerts to begin with, nor of many specific bands, plus as a weeb I do tend to quite enjoy my anime-related music. So, I think at least that would provide me with a more different experience that would be worth trying.
Edit: Oops, forgot to add a question. If you were the literal king/queen of the world for 1 day, with all the power and responsibility that entails, what would you do?
