I really dislike the idea of Libra becoming any sort of dictator. Her character is very much one-sided, we haven't seen her doing anything other than butchering entire armies, which is while very much appealing, is a completely different thing from ruling people. I don't think there are enough missions left in act 2 to show any other side of her personality, or to make any sort of organic chracter development possible. We haven't seen any sort of capability from her to think tactically, although it would completely make sense if she received a very extensive military training besides honing her psychic talents, it's not mentioned anywhere. And not only she's not charismatic, it's pretty much canon that only her clones can tolerate her presence on the long run. Ruling people just through brute force is not possible, intimidating people will only make them run away and hide at best, openly rebel at worst, some charisma is needed. More importantly, there's no clue that she has a desire to rule anything. She seems to be content with killing a few hundred soldiers every now and then.
I think her character would have needed much more elaboration, similarly to what happened to Yunru. Maybe in Act 3, if there's going to be one.
Her personality is nearly similar to Nero's. Except with a child-like temper and had psychic powers.
There is nothing to elaborate about it.
