Why would you (general YOU) get into fight? Because you may think that you are not man enough if you don't fight? Why would you think that you may not be man enough? Because you don't know whether you can truly handle your opponent or not.
When you don't know that your punch is strong enough to knock your opponent down, or your throw is skillful enough to take your opponent down, you will be more likely to accept the fight just to verify your self-confidence. If you have confidence in your "finish moves", it won't hurt your self-confidence to back up and avoid the fight.
You have to have fighting ability before you can talk about "inner peace". Without the combat ability, the "inner peace" is only a lie to yourself. There is a big difference between:
- Can do but don't want to do, and
- want to do but can't do.
After you have WMD, you can then talk about world peace. There is no country on earth that talk about "world peace" and not owns WMD and that's for sure.
