I view this as an "absolute" and to be an extremest view. I don't believe many things are either good or bad in any and all situations and circumstances. War is generally a negative outcome, but sanctions are far superior than boots on the ground, which involves bloodshed. Absent some kind of sanctions against NK, the NK government would likely commit their own acts of war against other countries that would involve bloodshed. There are also other military conflicts that produced better outcomes than the probable outcome had the US military not gotten involved.
It is possible that Griffith had similar viewpoints, and wanted to do something to make sanctions less effective (and of course profit in doing so).
Well that's great and all but his views really don't mean anything.
His views don't mean anything when he was working alongside the North Korean government to be doing some interesting things. If he had been working with individual people in North Korea -- not affiliated with the government -- to help them use Crypto so they'd be able to avoid the regime, no one would care and this guy would look amazing.
But he was working with the government to skirt international sanctions, and that's not something everyone can clap about.
