You aren't bothering anyone or doing anything not fully supported and intended by the game. I have absolutely no objections with how you're playing.
I'm still inclined to think your CMDR is a jerk, but you're entitled to play him, her, them, or it as thus.
I've never met any bounty hunter or anyone who would seriously consider a career in bond or bail enforcement that I didn't think the world would be better off without.
Of course, I've role-played plenty of bounty hunters, in games. I just never could find a way to convincingly portray the activity as a righteous one. Bounty hunters are mercenaries for a court system, the very best of which are profoundly flawed. Elite: Dangerous' dystopian setting is no exception here and 'good' people aren't shooting down others because some corrupt polity slapped a red sticker on their file.
My CMDR doesn't go out of his way to bother people, or stick his nose into business that isn't his. He appreciates similar consideration and acts to dissuade and deter activities to the contrary. Correspondingly, my CMDR is generally at odds with bounty hunters and pirates. Trying to take his stuff, or implying that one is willing to blow up his ship just because he's wanted somewhere, are not good excuses for much of anything, from his perspective. Self-defense on the other hand, well, that excuses a lot.
This is not to say my CMDR never takes bounties...indeed, he's claimed many thousands of them. However, these were largely incidental to his other goals and neither he (in-character) nor I (out-of-character) consider the activity as anything other than entirely self-serving.
Shooting people has worked pretty well, for my CMDR, thus far. Don't like getting shot at...don't scan my CMDR. Do like getting shot at, by all means, commence the scans. Some people certainly seem to like the challenge of picking fights while carting around non-combat utilities.
