I don't know about the need to be totally alone. I mean when you talk about the evil gods they invariably always have servants and even trusted minions. It's a very different kind of relationship dynamic for sure...one based on deception, fear, hatred, etc. But I think it would be a disservice to the origin story to have a fully enforced solo playstyle. Don't get me wrong here, it should be very difficult to bend companions to your will to faithfully serve you, even the ones already evil aligned, because evil after all is not sharing. But it should not be impossible.
If your working your way towards ascension as a murder god. Murdering everyone is kind of a requirement.
Sure once you become a god yeah maybe you could get some minions, maybe... But the game probably ends at full ascention.
Gotta remember this is Bhaal we are talking about if you are a mortal hes got an innate urge to kill you.
