For me, rather than horrible it was immensely annoying.

[Because he had to walk all the way back to the entrance of hell and even without Hades' troops up for a fight that's not a field trip.]

But yes, it was horrible for people, though now I have no idea what happens when one dies since both hell and Elysium were destroyed when we defeated Hades. I want to think that it can't be anything worse than that.
