How to make Primeapes fight each other properly?

[mksu]

Sometimes I will give 2 of them a banana and issue an attack command, but they will only kill each other a bit and then stop. Some other times they just go all out and have a civil war.

Is there a method to make it more consistent so the latter case happens?

I find that you need to have a good amount of monkey huts around (3-4) and befriending maybe one from each hut (if you see them spawn from the hut) will almost ensure a long battle. I think a lot of it also depends on whether the other monkeys are close enough to aggro and join the fight.
The point of befriending monkeys from different huts is that a long monkey fight actually isn't really a civil war. Lets say the different huts almost acts as different nations so if you befriend monkey #1 from hut A and tell it to attack monkey #2 from hut B the monkeys from hut B will defend monkey #2 and the ones from hut A will defend monkey #1.

At least, that's how it makes sense to me and how i usually go about starting monkey wars. Hope this helps!.
