Your considerations in opposing the hostage deal

But Hamas's continued existence is also a future danger, and in your opinion, this is not a consideration compared to a certain salvation in the present.

The continued existence of Hamas is not a future danger, but a certainty. And not a danger to individuals, but to the public.

And isn't the release of thousands of terrorists a danger to the public? And according to the law of large numbers, there is also certainty here.

The law of large numbers means that individual people will be harmed, not the public. It's about a tiny chance that any of us will be harmed versus the certainty that the kidnapped will be harmed now.

But even if Hamas remains, the chance that any of us will be harmed by it is tiny.

In other words, how is Hamas remaining in power different from releasing thousands of terrorists?

I don't understand what is unclear here. I explained that when Hamas remains, it is a harm to the public and not to individuals. Therefore, the chance of any of us being harmed is irrelevant.
A public harm means that our territories are under threat and it is impossible to live in them normally. That the army is on alert without a break, and repeatedly goes on operations.
