Team green would do something like that, If you remember s1x9 when they were stealing Rhaenyra’s throne. Otto ordered a kingsguard to assassinate rhaenyra and all of her children.
I think Otto would be willing to do that but he wouldn’t in that situation. Simply because it had no benefit. Same with Aemond. Aegon might have been hesitant but not anymore. Alicent probably wouldn’t be willing to do that even now. Larys definitely is doing it without hesitation. So basically it depends on the person.
