I can’t imagine anyone but religious zealots and people who don’t know any better that actually want to live in israel.
See, even the Israeli people know their government is evil.
This can also be bad in the long term as it’s likely that moderates and people against fascism are leaving the country now leaving behind the extremists and Zionists. The spectrum could shift more to being pro genocide amongst the remaining population and even if Netanyahu is somehow out of the government they might vote in another fascist.
If I were to guess the primary concern of those leaving it would probably be to go some place that doesn’t regularly have rockets fired at it
