Does using the word "vilify" indicate the author's attitude of confirming Genghis Khan?

Context:

Beyond his military accomplishments, Genghis Khan also advanced the Mongol Empire in other ways. He decreed the adoption of the Uyghur script as the Mongol Empire's writing system. He also practiced meritocracy and encouraged religious tolerance in the Mongol Empire while unifying the nomadic tribes of northeast Asia. Present-day Mongolians regard him as the founding father of Mongolia.[10]

Vilified throughout most of history for the brutality of his campaigns, Genghis Khan is also credited with bringing the Silk Road under one cohesive political environment. This increased communication and trade from Northeast Asia to Muslim Southwest Asia and Christian Europe, thus expanding the horizons of all three cultural areas.
