[Star Wars] How did Darth Vectivus rise to the rank of master if he did no evil? Surely he would have needed to kill his master to take his place?

Of course he was evil. He was Lord of the Sith. He had given himself to the Dark Side of the Force. Just because he supposedly died "surrounded by his loved ones" doesn't mean he wasn't up to no good. For all we know these supposed "loved ones" were alchemical homunculi bred from his slaves. 

It's important to keep in mind, that majority of this "Tragedy of Darth Vectivicus the Good One" was told by a scheming and twisted sith acolyte to her hopeful apprentice with express purpose to persuade him that it's possible to fall to the Dark Side and be totally alright.
