euthanasia it's a really hard topic... some people think it's wrong because it's like playing to be god, having a life in ur hands it's though, if the person is suffering too much, personaly i think they should stop the pain, living in pain is not living. But if there is any possible chance for them to heal, then you should give them a period of time to see if they get better, if u don't have money u will do anything possible to get it, because u probably truly care bout the person in this matter.
There is no actual way to know if you are doin the right thing... only time will tell...
