Underam hair is important as it gives a place for useful bacteria to grow. It also protects a very sensitive area. The bacteria stop the area becoming sore and infected. They do cause a smell if you do not keep the area clean, though. This smell is not your sweat, it is a by product of the bacteria doing its job!

Contrary to popular belief, if you just keep yourself clean your armpits should n't smell, even if you sweat a lot.

People who shave their armpits will need to use more deodorant, not less. They will sometimes get soreness and little hanging warts because there will be less "good" bacteria.
