[Undertale] all of these people seem really nice and friendly I don't think that most of them have any intention to kill me. Why do I die when I fail their minigame?

Aaron is only interested in flexing, froggit is just minding his business being a frog, and Washoua just wants to make sure I'm nice and clean. Hell, Shyren doesn't even approach me! She's in the corner! Why do I drop dead when I fail their minigames?

Unfortunately, you've come across the second reason for the Human/Monster war of old. The first is well known-- a monster that gains a human soul develops incredible power, which is plenty terrifying. But the second is this: monsters have inherent magic. They can hurt you **accidentally** just by being emotional near you.  Just by enjoying themselves, or by being sad, or anything... if they aren't consciously and deliberately suppressing themselves for your sake, their natural magic is quite liable to cause a nearby human severe injury. 

To a monster, this magic is harmless, and even aesthetic. They send each other "bullet pattern" birthday cards, for example. It's only humans who are always hurt by them. If you've never seen a human before, and don't really know much about them, why would you act differently around them, until it's made clear to you that this is a problem?

Of course, humans have their own advantages. Magic hurts them, but not nearly as much as PHYSICAL violence hurts monsters... to the point where a small human child is quite physically capable of genocide. There's a reason the humans won the war. 

If monsters and humans are ever to live together in peace, humans will have to be physically careful around their fragile monster neighbors, and monsters will have to be emotionally careful around their magically vulnerable neighbors.
