Also the confrontation thing, yeah big time. Moving up means more crushing downwards, which feels bad no matter what. Either somebody genuinely fucked up, and it's some degree of your fault for not training them right or catching it sooner, or they really did what they thought was right (and may have actually been the right thing) but a customer is mad or your bosses are mad or another department is mad, and you have to discipline them anyways.

You also have to fire people, which is probably the worst interpersonal interaction you can ever have at work, let alone in most areas of life. Again sometimes it's fully justified, and it still sucks, but plenty of times it's something like a layoff where it's "nothing personal, just the bottom line ya know", or it's that the bosses decided that this person needs to be fired for some arbitrary reason you may not even agree with, but you still have to be the one to pull the trigger and ruin this person's day/year. Additionally, you usually can't talk about the reasons with anyone else, so you have to field questions from the rest of your team that are usually good and valid, but you have to explain the away with vague corpo-speak and can't really tell them what's up.

So ya know, if any of that sounds fun, I mean, get checked out, because yikes.
