No, you don't. Which is exactly why its vital to develop the right character before you get to the crisis.
A (borrowed) story:
Once upon a time, in a land far, far away (well, Westminster Abbey is a fair way from here and it was a few decades ago), there was a big church service, in a packed Abbey Church with a lot of very imporant people in attendence. In walks a group of protestors. What they are protesting about has no direct connection to the service going on, but they are well known at the time for very quickly getting violent in their protest. Nobody is quite sure what to do and everybody sits there hoping someone else will deal with it. There are some police present, but dealing with it by force would be as risky as anything else. Until one not particularly senior clergyman gets up, walks over to the leader of the protestors and chats to him for a minute or so, then walks over to the person in charge of the service and talks to him, then goes up to the microphone and announces that the protestors will be given 3 minutes at the microphone to voice their protest and will then leave quietly. All then goes according to that plan.
That clergyman had regularly been seen before (and since) just randomly kneeling down talking to drunks in doorways and other acts of engagement with people on the edge of society, so that when the crisis came he (and only he out of a couple of thousand people) had the virtues to be able to deal with the situation.
You don't get that point, of instinctively being able to find the non-violent solution when the crisis comes if you regard violence as an acceptable option. Or if you don't do the rest of the characer building.
Editted to add: and yes it's risky. That comes with the Jesus territory, I'm afraid.
