I have some idea for some very historically realistic common negative traits

Divorced-With this man's luck with women what man would follow him into battle? Less likely to have children ((very realistic for Rome))

Satirist-People don't like being told how that their way of life is wrong, no matter how much divergence it has gained from the way of the ancestors -3 to influence, 10% less likely to win offices

Wife is an actress-Every Legionary has seen this man's wife performing, why has it not occured to this man to marry within his station? 10% less likely to win senatorial offices

Speculator-What type of man invests in slaves when there are citizens to hire?!!!! -5 influence, +15% to trade income, +15% to farming output, +5 to squalor

Mocks the Gods-"Why does this man publicly declare that the Gods are fake? Before his soldiers right before battle?" +10% to chances of gaining office, -1 Morale to all troops on the battlefield, -1 influence

Traditionalist-"This man has not only made all men hate him for excorciating their current values, but also all ladies hate him by insisting they should be in the hosue instead of in their shops and their professions, he furthermore regularly insults anyone engaged in trade, or lending, or anyone not born to their station"

Populares-"Thinks land owners should be kicked out of the senate and replaced with hard working good honest commercial investors"

Optimate-"Thinks all commercial investors should stay that way and out of the senate and perhaps even be declassed!"

Perverted Nutcase-"the Senate and People of Rome where shocked when this man married his own sister, tried to put up his horse Incitatus for elections, and started arguing with statues"
