Some bears just have a over aggressive personality. 95% of them would rather turn and run at the slightest whiff of a person let alone seeing one. Then there are the ones that can and will hurt you. Some can be very bold and come after a guy. That bear was a good one to shoot after he messed with you that much. I would have punched a tag on him as well in fear that someone without a gun might be his next target to mess with.
