The Underground is a depressing and horrible place ,to Snowdin a freezing town or Waterfall a swamp there monsters losing their mind from starvation , and even if you ended in a pitiful tired state at least you made it alive. Hotland however is a true hell , not only the unbearable heat is suffocating but you realized the danger of this as you stepped in a place recovered of sticky web used to wrap humans limbs , this time impossible to run or hide...you're at the mercy of the horryfing spider.
