You cannot have both wroth and kind traits.
Yeah its right but doesnt go well with both.
In RL, I can say that I have both.
Being kind, based on CK2, means you have a good heart and want to better the people you rule over. You do not like to bring harm to those undeserving and you have a genuine care for the peasantry and an urge to make them prosper under your command. (Of course, even the kindest of men will punish their enemies who try to kill them and their revolters, so that doesn't mean they are pushovers.)
Wroth, from the same root as "wrath", means you are very easily angered. You have a hot temper and you have been know to verbally lash out at people. You yell a lot and are easily set off. In rare cases where this is put to its extreme end, you can also be physically violent.
If you are Kind and Wroth at the same time, you have the deep seated urge to better others and be nice to those you do not know, but you are easily set off and angered at trivial things, even against someone you love. Being wroth when you are also kind is very painful because you will lash out at those you love most and have to deal with the horrid remorse that yields.
It's not a good way to live.
