What may be generally perceived as good and beautiful can become evil and ugly when exceeded to a certain degree. What is often perceived as evil is then a counterbalancing counterweight. Opposites have their limits beyond which "Death" occurs. 

It need not be physical death immediately, but also "just" the transformation of the state into the Right or Left opposite, like a pendulum or a balance. Like tightrope walkers, we balance and walk between quanta of possibilities.

Left or Right ?
Calm or Active ?
Inward or Outward ?
Act Negatively or Positively ?
Enjoy the Darkness or the Light?
Looking Up or Looking Down?
To be a self-centered Selfishness or a Martyr who gives himself away for others?
To be guided by Reason and Rationality or by Feeling and Intuition?
Preferring the Father Principle or the Mother Principle?
To be bound by the Order of the Intellect or to submit to the Anarchy of the Body and the Instincts ?

If we remain for a long time in an extreme situation, suffering and sometimes even Death come, and it does not matter whether from the Left or the Right, from the Abyss or from the Darkness...

Extremes point to the need for Harmony.
Is there not a third way after all?
The Way
