Those "sworn murderers" would be a tiny minority with no support, like any openly-racist group in most societies, if the mainstream wasn't so openly discriminated against by the same folks the "murderers" purposely hate.
Most armed movements in contested territories are historically overcome not by "subduing", but by actually addressing the grievances of the mainstream population who helps them. Look at Northern Ireland: the IRA was never defeated by military means, but they were engaged politically to solve the mainstream grievances that were well-founded: removing most anti-catholic discrimination across society, allowing free movement across the Irish border, and allowing each person to define themselves as Irish if they wanted to (rather than British). Until Israel takes a serious integrationist approach that removes its apartheid-style structures, the mainstream in Gaza will continue to support armed resistance, because they have nothing to lose from doing so and nothing to gain from not doing so.

No, it's just fatalistic shortsightedness. If you can't imagine a better world, obviously you can't build it.
> Why do the Indians own more property in London than the British?
Because they resisted their occupation, reclaimed their immense land and resources, and fought to get back on a level playing-field. Definitely not because they accepted white-man rule!
(And if you claim that living in London is something to crave, man, you've probably never been there for more than a week :)
