I think you need a lesson of history, so I will mix two of my older comments here:
Israel became an actual state in 1948 by displacing 750 000 Palestinian people and murdering many (men, women and children). Laying sieges, bombarding villages and population centers, setting fires to homes, properties and goods. Planting mines among the rubble to prevent any of the expelled people from returning (source: The Ethnic Cleansing of Palestine by ilan Pappé).
Now Hamas did not exist until 1987, they became an actual group only in 1987 because of all the actions Israel had done from 1948 up until 1987. Which is approximately 39-40 years after what Israel had done to the Palestinian people.
From this we can conclude that Hamas did not start this but Israel did and that Hamas is fighting back.
Israel is currently doing:
Stealing land
Ethnic cleansing
Genocide
Calling Palestinians rats, animals and more cruel things
Wanting to erase the entire Palestinian race
Lying to the world
They think they are “superior” than Palestinian people
They think and say that Palestinian people are, the “inferior” race
Apartheid
Sent Palestinian people jail/ prison for no reason (even kids)
Beat Palestinian people for no reason or provoke to “get a reason”
Does these things ring a bell? I’m sure it does because the Nazis were doing the same thing.
There's an image which shows the very similarities between Nazis and Israel government.
