From my experience playing Crusader Kings 2 and 3, gavelkind’s a bitch.
Splitting your enemy’s demesne amongst their successors gives you more but weaker enemies (and sometimes some friends), and leads to infighting and chaos amongst them.
Nine times out of ten murdering an enemy with lots of children leaves you better off than not murdering them.
(Of course, though, this scales inversely to the number of successors, so if there’s only one or two proceed only if their stats are lower than your enemy’s, or if it’ll still be a few years before they come of age.)
