Im an assassin............ ?

Im Ezio auditore da firenze like my ancestors before, im an assassin. Lately ive been threatining duccio because he called my sis a puttana. I called him stronzo and fottiti. And punched him after. Is this okay? I just care very much for my sister, sometimes i urge to get my poisened blade and make him suffer but hopefully a dog full of rabbies will kill him, lol. I even got lanz the footpad to help beat him up (he is leader of cento occhi) is this bad too? I wish alta�r was here to lead me but can you help.? Thanks Amico :D and friend another last question do you think i should assassinate lecrezia borgia in siena.? Or venezia or do you much prefer alhambra or is that notorious? Hmm perhaps pienza. Please vote for what place!
