It's when you say things like "Who are we to judge right? I don't think that anyone watching from a distance liked what they saw with respect to that incident but I certainly know nothing about what led to it", it makes it sound like you want to justify it.
Sale was out of line in that incident, and several others preceding it. The Red Sox benefited because it all did lead to his trade out of Chicago. I don't think it is any coincidence that Sale and Eaton were the two most critical players on the White Sox for the whole incident, and they were the first two players traded away, despite both being on team-friendly deals that teams rebuild around rather than trade away to rebuild with.
But really, that entire scenario was the fault of Adam LaRoche and Kenny Williams. LaRoche for putting the team in that spot to begin with, and while Williams really probably did do the right thing, he allowed it to escalate into a war with his players. But this in no way justifies anything Sale (or Eaton) did, which was a lot, and it all culminted with the incident of him cutting up jerseys.
But hey, it helped the Red Sox get a ring and he has been much better behaved since coming to Boston...
