So far, your expressed beliefs have proven to be misguided and/or wrong.
A 17 year old with very limited experience handling firearms illegally obtains a deadly firearm and goes to a neighboring state where there are ongoing protests and vandalism following a recent police involved shooting.
Upon arriving in the neighboring state, 17 year old Rittenhouse stops at the home of his friend/accomplice in the illegal firearms purchase, picks up his friend and illegally obtained firearm and heads to the site of the ongoing protests, purportedly to protect a business at the request of it’s owner.
Rittenhouse’s friend stations himself on the roof of the business, while 17 year old Rittenhouse, a minor with very little firearms handling experience, and carrying his illegally obtained firearm in violation of WI law stations himself on the ground “protecting” the business.
A claim that is partially refuted by video of Rittenhouse walking around with his M&P 15 casually slung across his chest, wearing a homemade “medic kit” on his belt, asking groups of people engaged in conversation (not rioting, looting, or committing arson) if they need 1st aid, telling them that he is a trained EMT (a lie, of course).
Already proven by his own actions at this point to be severely lacking in judgment and driven by a pathologic need to “save people”, untrained in the safe handling of weapons (His friend/accomplice in the illegal straw man purchase, Dominick Black, told investigators that Rittenhouse’s shooting skills were “horrible”), with his loaded long gun, was the very definition of reckless endangerment from the moment he arrived at the protest site.
And I haven’t even gotten into Rittenhouse’s previous troubles.
