This is from Beelzebub's ethics: Destruction and War.
.."Father Satan has dictated to us that there will be a time when negativity will slowly become replaced with positivity in this world, but this time will only arrive when we advance and progress tremendously – and we are very far away from this state.
The arrival there will happen through our War, a necessity for our evolution. The current state of duality in the world is currently a foundation that cannot be denied in this reality.
War can be mitigated and should be avoided. War represents the ultimate and most reckless form of competition; there are other and better forms to manifest this.
Until then, in conjunction with realism and the natural order, war is undeniably yet another aspect of life. It must be accepted, avoided, or even practiced under very necessary circumstances in accordance to Wisdom.
Devoid of Wisdom, the power Ares represents will only be a detestable form of no essence to itself.
We must learn to fight and to even destroy, for only then we can escape from this Ancient brute ruler of life. Through winning the inner war, we avoid external war."
When specified to what you're asking, there are many possible outcomes to how, "destruction of our adversaries, and eradication of suffering," might look like in the future.
Read and meditate on this virtue and the virtue on Justice to help give you a better understanding.
