Strategic or stupid? I've been doing it a lot lately. Like when somone sticks me with a rad, or somone's chasing me.
Idc, I always suicide if I can when I get a rad nade one me. Usually against rad players (especially in 1v1s) it'll get to the point where they're just trying to stick a nade to you the entire game and run away because they know they can't out play you.
