To me it is kind of a tough call.
Hard to fight for anything if you are dead.
To save people you care about sure. For an idea, I don't know.
There's no guarantee that when you die your ideas won't die with you.
While you are alive at least you can continue to act. Maybe do some good in furthering your cause.
I suppose dying for an idea at least creates a good narrative for others. In Jesus' case, Christianity seems to have done as much harm as it's done good. If Jesus had lived to continue to teach perhaps we would now have a different Christianity.
I think some people misread the thread title
I do not mean that death is better than freedom.
I mean that our goal is to make life worth living by fighting for freedom.
So...sure...fighting for making life beautiful and good, is the first thing to do.
But not at cost of freedom's sake.
