For the palestine situation, hamas leadership has generally fared poorly (no tears from me, they started this war after all). However you can't issue a warrant for a dead person.

There aren't two sides in genocide.

It should be noted that the ICC has not as of yet alleged that anyone has comitted genocide in palestine. All the (public) accusations thus far have been for lesser crimes. There is a big difference between what randos on social media are alleging and what the ICC prosecutor is alleging.

Furthermore, everyone has the right to be pressumed innocent until proven guilty. That includes people accused of heinous international crimes like genocide or crimes against humanity.

(To date, the only person the ICC has ever accused of genocide is Omar al-Bashir from Sudan)

The severity of an accusation does not imply accuracy.

There are two sides in this conflict. Israel denies these allegations.

Some on the other side are openly calling for the genocide of Israel - while claiming that Israel is doing it.
