Idk man you're quoting a rule given to some humans vs an act carried out by angels, but even disregarding that, the idea that a divine being has to act the same way in all possible circumstances like a soulless robot is also a weird notion, a stronger argument is that Jesus's power level was on a whole other level such that he didn't have to fight, he was able to simply command, whereas angels are on a power level that requires actual battle, and this difference makes sense considering Jesus's main objective of helping humans in spiritual warfare not a battle of flesh and blood
