Fast unto Death?

I wonder if we should support any "fast-unto-death". While I believe it's blackmailing the concerned people, when something is so freaking important what do you do? But then there can never be anything more important than human life. Perhaps we shouldn't support it just because human life is so important. But then again what about it when it actually tries to protect other many more lives? God, why can't there just be right or wrong? No I guess it's wrong! There should be other ways to protect human life and the loss of one most definitely will not ensure the safety of others!
