Would you really die for someone?

[IsraelYabuki 439]

I'd gladly die for my little brother to save him

[DubWolf 16,617]

One big condition need be met for me to be fearless enough to go as far as to sacrifice myself.

That or the sudden impulse to save them knowing how important they are to me and how I'd feel regret if I didn't save them, or feeling terrible that they experienced such a fate.
