I expect the IDF to fulfill their obligations under the Geneva Conventions, the ICCPR, the CRC, and all the other treaties that Israel has signed and ratified. And out of you, compassion. Are you capable of it? What exactly does "finish the job" mean? And what does the IDF gain by disrupting ambulance progress, running the ambulances, hospital generators and everything out of fuel (the generators are even then needed because the electricity is cut) and running the civilians out of water?
If Israel cannot act like a civilized nation then what moral high ground are they asserting against their avowed "terrorist" enemies? Is it too much to ask them to allow the care of the sick and wounded and the fulfillment of GC4 Part II? Even the IDF and the MDA don't really think so. They are facilitating some supplies and help right now, only disputing how much and whether or not they are complying.
Only their so-called "supporters" like you want such a lack of compassion. Only so-called "supporters" like you are acting like there should be no peace until you've lapped up every drop of Palestinian blood. Are you proud of such hard heartedness?
