Hamas has a clear charter and consistent speeches; liberating Palestine from Israeli control. You might not trust them but they’ve been consistent in calling for a Two State Solution since 2004, they kept the majority of ceasefires (Israel broke more ceasefires over the last 20 years than Hamas did) and since Netanyahu has spent years undermining Abbas it means Hamas has more public trust than he does. I don’t trust Likud either since their public charter calls for the total elimination of Palestine, but he’s in power and have to deal with him.
You act like releasing the hostages would end the war. Netanyahu publicly promised that even if all hostages were returned the war would not stop. That’s why he refuses all offers for a ceasefire in exchange for all hostages. He doesn’t care about them, and Israeli protestors and the opposition parties agree.
Likud wanted this fight, and could end it by allowing a two state solution. That would even undermine Hamas politically and give political credence to Abbas and other moderates. But Netanyahu intentionally spent 17 years obstructing that and trapping himself into this corner he made for himself.
