I think the overall point that could be made is not about how useful the help is on an absolute basis, but rather how petty it is compared to the devastation that Palestinians have been subjected to for decades, regardless of the presence of terrorist activity.

The overall injustice that Israel and the IDF represents over the whole timeline is staggering. Pogroms, massacres, bulldozing homes, murder of peaceful protestors, monetary contributions to Hamas, apartheid style laws, and not to mention the now extremely prejudiced bombing of Gaza where they are cut off from resources, and cannot even freely evacuate.

Israel has historically, and now quite directly, placed the Palestinian people into an absolute meat grinder. In the context of this, sending fuel to a hospital is clearly bad faith, even if it was guaranteed to last a week instead of a day.
