Lol and then he goes and instigates a massacre of Roman citizens. All because she made him realize he has to kill Romans to eventually get to Spartacus. I like to think he's now doing it partially to get revenge on all her rapists/torturers.
They would've massacred the Romans anyway, he didn't do much to incite the masses - and killing the brother who was choking the guy who had raped his sister could be considered a mercy kill as well. Caesar is far from my favourite but he came across as sympathetic for the first time imo.
