Why can't people with AIDS have the option of suicide or euthanasia when they get sick?

"This will control the disease'? God, little cold aren't you? For that matter, why not 'put down' the elderly? they have no future either. Or how about pre-me babies, so they don't have to go thru the hardships they have to go thru? Or how about those with any health problem? "And decrease the surplus population!" Eh, Scrooge?
