Those with kind hearts who obtained power were able to help more people. Yet those with malicious hearts who obtained power caused destruction far greater than before.
Like the local ruffians who, prior to awakening their bloodline due to limited abilities, could not commit major evils and were only capable of petty theft and extortion.
But now, with the awakening of their bloodlines, these scoundrels suddenly possessed great power. The evil thoughts suppressed in their hearts were unleashed — small thefts and extortion could no longer satisfy them, and they began to progress toward bullying and abusing others, committing rape and pillaging.
The stronger their power, the greater their capacity for evil. Compared to monsters, these evil men were worse, because while monsters merely consumed humans, these men made lives worse than death.
"Alas!"
"Changing the world is easy, changing the human heart is difficult."
