lmao....i think any normal living creature would WANT to stop suffering haha. I disagree with your point on selfishness though, what if someone was in agony every day and night and in the hospital and wanted to pull their own plug, but a family member just couldn't let them do it for w/e reason....couldn't THAT be considered selfish by the family member to want to prolong someones suffering for their own "selfish" emotional need as opposed to someones immediate physical need?
Selfish can be a very objective term.
