Getting killed by the IDF smuggling relief supplies into or people out of Palestine is dying for a cause. Going to fight and die in Ukraine is dying for a cause. Running into a building to save people is dying for a cause. This wasn’t dying for a cause any more than if he’d gone on a shooting spree or blew up a building and said it was for Palestine…simply saying Free Palestine while committing suicide contributes nothing to the issue aside from more tragedy.
