Almost by definition, any "obsession" is likely to beharmfull. That being said, however, deer hunting itself can become an obsession regardless of what the end result deer taken is. So can an obsession with hunting itself corrupt hunting? Of course not. I think any hunting obsession, be it killing a big buck, killing any buck, killing with a certain weapon,or even killing anything is just fine for hunting as long as we recognize that not everyone is obsessed and certainly not everyone shares the same obsession. IMO the harm/corruption begins when a hunter or group of hunters decide that their particular obsession should be everyone's and start trying to push their view on others. So to answer the question "is the obsession to shoot big bucks corrupting bowhunting", I say no it's not. What is corrupting it is the attitude and willingness of many that share the big buck obsession to look down on other hunters ways and even try to legally force their obsession on them.
