There's...literally footage of the man & his family leaving their home into the tunnels, Sinwar personally carrying the TVs & armchairs & household conveniences, man. Stop.
The only reason he resisted right at the end is he got caught out in the open running from hidey-hole to hidey-hole, stumbled upon by some super-junior IDF randos with his pants proverbially down. The guy was underground *for a year* without joining his men to so much as fire a single shot. You know this.
He had no choice but to go out that way, he was dead the moment they found him and he knew it. The guy would *much rather* it didn't come to that, he wasn't actively & heroically seeking out a firefight with the Israelis or however you want to frame it with mental gymnastics. Guy was cornered, the boot was coming down, he was Hiding and they were Seeking, the seekers won out, all it was.
As for the "go back to New York or Berlin or wherever you came from" directed at the soldier, "Israel" is the word you're looking for. The answer's Israel, the place he's ensuring stays with his people. The people, you know, from there originally. You might as well be asserting Native Americans are colonizers or something, it's just as laughable.
