Bread on Kamino and trained for the Grand Army of the Republic as a medic, clone CT-2080 "Doc" was a combat medic. He disliked fighting for a government that didn't care about its troops but disliked the jedi even more for there hypocritical moral views, trying to make the galaxy a "better" place but still not having a problem with commanding a "slave army".
Despite all that he stayed to help out his brothers
Order 66 was a dream come true for him, getting rid of the thing he hated. And soon after the Empire started adding cloning from other hosts than Jango Fett to fill the ranks and a little after that even enlisted civilians.
The Empire began to have less and less of the original Fett clones which Doc didn't care for and slowly started to plan to desert the Empire. The best way to do so would be on a planet with little imperial control.
Stay out of the hands of the Empire and try to make a living for himself and any other clone deserters.
