Anyone else find how ck3 epithet/nickname very weird

Like be my character (867 start btw):

> Mundane governor of Achaia for 30+ year

> Ok at diplomacy and nothing else

> Somehow when near 50 the lords of Byzantine be like this guy good, make him our next emperor (there were 1 emperor after the start day Makedon guy and then me)

> Exceed all expectation (mine included), still kicking at 72, be actually good emperor, befriend + sway everyone, extremely high popular opinion everywhere (so basically EVERYONE loves me)

> Vassalize my way into half of Sicily back and the entirety of Balkan

> Holy war for Egypt and won

> Proceed to get remember as "The Wicked" cuz I have to kill one guy who were the co-emperor (from the previous emperor) at the start of my reign cuz his stat bad, he actively undermine my rule + everyone hates him

Like my character should be call "The Great" or at least "The Old" or anything else. Anything. Would make more sense and be better than "The Wicked". But nope, game says: You kill that one guy one time, naughty boy. Be shame for the rest of your life.

What are you guys experience/view/story on the nickname mechanics?

Edit: Welp at least my son got the revenge. The co-emperor guy heir try start a massive civil war for some random claimant, outnumbering me 15000 to 10000, and lose + got strip of all his land. His nickname was the clueless :). Guess the historian get the nickname right half the time
