So what ways do you think that the aspects could negatively impact the players?

Aspects are supposed to embody something about you, and as such they also embody negative traits. No Aspect is fully positive, no Aspect is fully negative. As such, whether it’s you being overcome by your Aspect- Say, a Rage Player going Berserk or a Void Player just fading away into Irrelevancy- Or you refusing or being unable to control your Aspect- Like a Life Player bound to servitude or a Hope Player having a Crisis of Faith, there’s a myriad different ways anyone could struggle with their Aspect. They are innate tendencies and leanings, but whether you need to find a balance, get more of your Aspect, or not let it get to you, it all depends on you individually.
