No. A vigilante acts out of a perceived notion of 'common betterment of the community', 'fighting evil' and such. A bounty hunter wants money. For himself. I dont care *why* someone has a bounty, whether it was justified or not or how serious it was: you pay me to kill him, I kill him. A bounty hunter is closer to an assassin, acting against the law if needed.
BH'ers are bungholes. Vigilantes are wannabe-heroes.
Hmm - clearly your view of the world is not particularly wide.
There are plenty of real life bounty hunters that do it because the police cannot be everywhere all the time. Some are retired police, or those that cannot join the force for whatever reason, but have the skills to be a bounty hunter.
In America where bounty hunting is a recognised profession a great deal of them deal with criminals who have skipped bail, or are wanted for other reasons, but not so serious that a dedicated police task force is warrented.
Here is where the bounty hunter shines - he (with or without a team) can track and hunt down the individual either to point of arrest (they have limited powers, given to them by courts) or to the point whereby the police can then take over.
They can cover huge areas for much less manpower and cost.
If you honestly think they do it "just for the money" with no "common betterment of the community" in mind - you should follow some of the american TV shows about it - it's a crapload of work and hassle for not a lot of money, and there's always the risk of actual RL death when chasing a bounty with access to firepower and not much reason to come peacefully.

You've been watching too many fims mate - this is so far from reality it's laughable - BH's in RL have no "licence to kill", not even under extreme circumstances - they have to abide by the same laws as normal citizens, if there is a homicide they WILL be taken to court and put on trial, just like everyone else and they will have to prove beyond any doubt it was justifiable, or go to jail, just like everyone else.
The fact that the Bounty mechanic in ED gives you a bounty for the tiniest thing is an issue with implementation of that mechanic, NOT how a BH player reacts to it.
In ED this should be the mechanic that re-vitalises the "bounty hunter" profession - actually making it a profession, rather than something a player just does as part of a mission "for the money".
You say BH's are in it "just for the money" - you're right in ED that's all it is, because there's no other mechanic to make it a PROFESSION - BH in ED right now is just another "fetch" mission.
As for the Vigilante's being "wannabe hero's" - these only happen because there's no police around when it matters - which nowadays is most of the time.
