They didn't have "all the citizens slaughtered", they enslaved them. As usual. Of course, some were ritually executed. As usual.
You're reading way too much into Roman propaganda. Look how they were OH MY GODS outraged whenever their captive soldiers were being sacrificed (by the British druids or the German witches), or by the Gaul practice of headhunting, despite routinely torturing their own prisoners to death in public (including but not limited to crucifixion) or forcing them to kill each other in what they called "games" for the enjoyment of what they called "mob". Hypocritical pricks. Nice civilization tho. Even if just culturally appropriated from the Greeks, after murdering their way all through Greece.
Btw they also honestly believed, or wanted their people to believe, that Christians were literally bloodthirsty cannibals.
