When she was little Sarah Kerrigan exploded her mother's mind and brain-damaged her father. Absolutely no training, nothing but raw psionic power, and she blew her mother's head apart and permanently damaged her father. On accident.
And then she got
trained. And then she got
enhanced by the Overmind.
It really comes off to me more as a bad idea than anything. This is a woman who could blow heads apart with her mind when she was like,
eight and then she's only gotten stronger and actually trained.
Anyways
@torroar said this isn't really relevant atm so Imma gonna drop this tangent.
