Remember the old saying "one person's terrorist is another person's freedom fighter?"
Terrorism, in its broadest sense, is the use of intentional violence and fear to achieve political or ideological aims. State terrorism is that perpetrated by nation states, but is not considered such by the state conducting it, making legality a grey area. "Terror is nothing other than justice, prompt, severe, inflexible", said Jacobin leader Maximilien Robespierre.

For arguments sake, I'm going to use these two definitions:
"the deliberate killing of innocent people, at random, to spread fear through a whole population and force the hand of its political leaders" (Michael Walzer, 2002).
"the organized use of violence to attack non-combatants (‘innocents’ in a special sense) or their property for political purposes" (C. A. J. Coady, 2004).

So let's look at the numbers for the Israeli-Gaza conflict.
Hamas: Out of the roughly 1,200 people killed on October 7th

The most recent death toll from the military had 318 service members killed during the attack itself (37 more have been killed since the IDF launched its ground offensive in Gaza), with police citing another 59 dead. Such figures include armed fighters who tackled the terrorists head-on, but also unarmed service members in non-combat roles who were killed inside their bases, sometimes in their beds.
Police said they have identified 845 civilian deaths.

So roughly 45% of the casualties were security forces (none of them babies).
Now there's no possibility of knowing how many Hamas fighters have been killed since October 7th. So just assume that every Palestinians adult male killed was a Hamas fighter. That would obviously be an exaggeration, but let's say that anyway.

IDF:

Since October 7th, 2023, more than 10,300 Palestinians have been killed, including more than 4,000 children and 2,700 women, and more than 25,000 have been injured in the Gaza Strip, according to the Palestinian Ministry of Health (MoH).

There are more than 2,200 persons reported missing in Gaza, including 1,270 children most are trapped under the rubble. According to the Palestinian MoH, more than 70% of fatalities are children, women, and the elderly.

So who is the greater terrorist?
