'wolves do not normally kill just to kill.'  
that is true.
on the other hand, there are untold numbers of humans who do kill for the fun of it.  
they shoot wolves from airplanes and bears at bait stations and strangle cubs in their dens, all the while claiming that they are providing a desperately needed service.
   
dealing death is what it's all about.
  
killing stuff. 
     
those lofty claims about 'managing' game populations and how the killers pay for said 'management' are  nothing more than lame justifications and excuses for limbic barbarism.
