I highly doubt it.
Bar one line, that almost-exact quote
The greatest traitor has always resembled an honest man and the greatest falsehood comes across as truth.
Righteousness and evil cannot be discerned by their appearance.
People have decided wrongly about me in the past.
Today they still misjudge me,
and may continue to do so in the future.However, I shall remain myself.
I have never cared about others misjudging me
can be heard from 31:24 to 31:46 in this video, which is an episode from the 2010 TV series, which itself is mainly based on The Romance of the Three Kingdoms, which in turn is a novel loosely based on the Records of the Three Kingdoms.
Chinese transcription of the quote in that video:
...大奸似忠,大僞似眞
忠義和奸惡都不是能夠从表面就能看得出來的。
也許你們从前錯看了我曹操。
現在又看錯了。
可是我仍然是我,
我从來都不怕別人錯看我。
I cannot find 大奸似忠,大僞似眞 in either the Records or the Romance.
Well, the Romance was supposedly written in the 14th century. According to this Baidu article, The greatest traitor has always resembled an honest man (大奸似忠) first appeared in a Song Dynasty text (宋・邵博《聞見後錄》), so such a quote cannot possibly be attributed to the historical Cao Cao.
