We have a number of tools at our disposal as drivers to minimise bad situations. Personally I think overuse of high-beams is more valid than under-use in quite a number of circumstances (and exceptionally bad in others).

Your comment implied that drivers who instinctively switch on their high beams to get a sense of a situation where they need more visual input are "jackwads" which I tried to highlight isn't the reason they're doing it.

Wanting to see more when you're driving a massive piece of machinery at decent speeds isn't something that makes you an outright asshole.

Those points weigh in favor of someone who thoughtlessly high-beam'd a pedestrian, for the first time - which is reasonable. Also reasonable is considering their actions and realizing they gained no meaningful amount of safety by blinding a pedestrian.

If they've blinded countless pedestrians over an extended period, then they aren't considering anything. Inconsiderate people are jackwads.
