In Buddhist Jataka stories you find Bodhisatva (Buddha in a previous life) sacrificing his life to feed hungry animals etc. However, in Sutta what you find is the practice of the middle path or Noble Eightfold Path.

Self-sacrfice for me is doing the washing up in the temple (or anywhere else for that matter) - I'm doing it in service of the dharma, other motives (besides obvious practical ones) are wrong (this is on a good day btw, normally I'm doing it because I'm told to :)).
Other types of self-sacrifice often look to me like acts of extreme defiance coming from anger and ego, but I think it's a matter of choice ultimately.
