You've committed treason against your country and you are on the run. Your country is not so willing to let you off the hook, and has placed a sizable bounty on your head. Work with your DM to decide how large your bounty should be in correlation to the gravity of your crime. Regardless, this bounty forces you to stay on guard and your character should hold a level of caution unless a component of their personality tells them otherwise. Likewise, you can ask more self aware questions than a D&D character should normally be able to because a War Criminal often carries a level of paranoia. If you are confident in your abilities or calm and collected in nature, this perhaps holds less true but you would instead likely be a better lier. Your character might have a second life, a persona that they use to stay in hiding. Unlike a Charlatan, however, the second life should be the only one you use typically, as you don't want your past to catch up with you. It should be the name on your character sheet, with your former name being listed as an additional feature or trait. If you want, you and your party can choose to turn you in, collect the bounty, and then break you out if they want to collect the reward for themselves. Depending on how that works out and how they roll in that time, they might accumulate bounties themselves or maybe the people who broke you out remain unknown.
