Probably not. Teenagers are still developing their brains, empathy, etc.
Some teenagers are taught that hunting is a valuable skill and want to practice it. Some just want to use their toy and don’t actually consider the full implications. Some might have been taught that squirrels are vermin.
All those things are more likely than the teen shooting the squirrel because they enjoy causing pain. Probably the squirrels POV never even shadowed their thoughts.
tl;dr teenagers are stupid and do stupid shit without thinking about what they’re doing.
