He's the personification of a very large aperture and a (so far) thin depth of field. His prints merely hint at what he might do -- and, personally, I think a little more sharpening would go a long way towards making his good images excellent. For now all we an do is guess and wish him good light, and, particularly, a robust set of back-ups.
We would do well, though (imho) to slip a more nuanced scale under the needle of our judgement. The gamut of human action is much more complex that a line fixed to "Hero" on one side and "Criminal" on another allows. Even in the supposedly distilled world of military engagement "Hero" and "Criminal" reveal more about those who use such labels than the actions themselves. The murderers at Béziers were surely heroes, if only for a day (when better armed heroes tried to deprive them of loot), as were those who bombed Pearl Harbor.
