You should still avoid death as much as possible. People are always willing to die a heroic death, but in reality, the situations in which a death is mathematically worth it are few and far between. For example, a jungler smitestealing a dragon or baron would be worth it, but if you died to try and save an already death person, that wouldn't be worth it at all.
