You may not be able to get rid of the gene completely, but it is better to reduce the amount of these deer and have the deer with good genetics thrive then have a lot of cull bucks running around. Who wants to look at a bunch of messed up deer while hunting? Plus, if you have a year with a limited food supply(drought, cold winter, etc.), these deer will be eating food that could go towards bucks you are trying to grow as big as possible.
