The guy who tried to shoot Jackson had his gun jam on him twice. While I agree that Jackson was well within his rights to disarm the guy and make sure he wasn't going to try a physical attack, he beat the guy to within an inch of his life.
Andrew Jackson showed that he could take care of himself even at an advance age using a cane. This person meant him bodily harm, and he had every right to defend himself. I say it doesn't make him more violent just more brave proving that he was someone who could take care of himself.
No, Andrew Jackson beating a man who tried to assassinate him with a cane does not make him appear more violent. Andrew Jackson was merely trying to defend himself, not trying to become more violent. Anyone else would have done the same in that situation. Not trying defend oneself when being assassinated is against human nature.
Andrew Jackson was one of the most violent presidents we've had in office, but that was due to his military background (including a time as a prisoner of war) and his willingness to use force when others would balk. While the story about Jackson beating a man with a cane shows a glimpse into that side of him, it certainly doesn't make him appear more violent than he already was.
