I felt much the same as you when I first got into DE shaving, but am now an unashamed badger fan. My reasoning is thus:
As I understand it, Chinese farmers will continue to trap wild badgers as they are a threat to their crops and therefore their livelihoods whether the hair is used for shaving brushes or not (the European badger as seen on Springwatch and the like is protected and not made into brushes). On that basis, it seems sensible to me to respect the creature by using the hair rather than wasting it. Plus, whether we buy the brush or not, the badger is already dead.
An alternative may be a horsehair brush from somewhere like Gifts&Care, as the hair is obtained through grooming. I have no personal experience with horsehair brushes, but other members here do and can advise on which model(s) would be best suited to your needs.
