Reminder:
* The last parlimentary election held in Palestine was 2006 [1].
* The median age in Palestine as of 2023 was 19.8 [2].
* The voting age in Palestine is 21 [1].
In other words, the majority of the population today were born after the last major election, and they aren't voting age now, let alone at the time of the last election. When you account for people who were voting age in the last elections, the number of people still around today is a rather small minority. It shrinks even further when you consider that Hamas only got 44% of the votes for Parliament (alas, due to how district votes are handled, that gave Hamas 74 of 132 seats).
Given that, I'm a little less sure about holding the current population of Palestine responsible for Hamas. You could argue they should be doing more to displace Hamas, but perhaps that can wait until after they're done worrying about starving to death or being shot by IDF snipers while accepting food from aid workers.

My other experiences with Palestinians revealed that they're very empathetic people and they integrate quite well into other cultures when they're not bombed or shot at.
A year prior, they had documentation of a plan like what unfolded on October 7th, but dismissed it for reasons I won't speculate on. Google 'Jericho Wall'.
Approximately 3 weeks prior to October 7th, Unit 8200 produced a document based on months of research, that showed Hamas seemed to be doing a lot of training and coordinating for something.
In the days prior, Egypt warned Israel that something big was happening imminently, but again, it was ignored for reasons I won't speculate on.
The night before, the IDF identified a number of anomalies in Hama's behavior but did nothing with this information.
A number of members of the intelligence and military leadership have stepped down since, acknowledging the failures.
Anyhow, for whatever reason, your belief that this was completely in character for Hamas, seems to be at odds with the beliefs of Israel's intelligence and military community in the months and days prior to the attack on October 7th. Which is, odd, to say the very least.
