Make a good RP story. Mine for example, for my Rogue character Ketzel:
His daughter was raped and then killed when it was found out she was pregnant by a Kusari diplomat's spoiled son. My character went to exact vengeance on the kid, but didn't manage to kill him. He got caught and sent to Sugarland, from where he managed to escape and join the Rogues. His mission in life is to find this kid and to kill him. To do so, however, he needs resources, and since he can't get them legally as he's an escaped convict, he pirates.
Just an example.
Thanks to MikeyH for the banner.
