Can beings, that are neither 50% STS, nor 50% STO ascend

[Infinite]

edit: 95% STS*

Hey, I was wondering this.

It doesn't seem good, nor logic to me, that they can't ascend, even though source is willing to experience every kind of experience.
I mean, what if a being likes to make others suffer, but there are a couple of beings which it likes and which it helps. Is such a being supposed to stay in it's present density forever?

It's a matter of "vibratory ressonance". The entity that doesn't achive the minium degree of STO or STS polarity can't support the fourth density vibration. It's not about fair or unfair. But laws of the universe.
