It is not enough to be compassionate. You must act.
There are two aspects to action.
One is to overcome the distortions and afflictions of your own mind, that is, in terms of calming and eventually dispelling anger. This is action out of compassion.
The other is more social, more public. When something needs to be done in the world to rectify the wrongs, if one is really concerned with benefitting others, one needs to be engaged, involved.
