Did M actually have a point?

Also, M tells Bond that his vendetta against Franz Sanchez could lead to a major scandal. He says point blank "This private vendetta of yours could easily compromise Her Majesty's government." Sure, M does come across as a cold and condescending jerk with the way that he goes about it. But still, he does have a point when you really think about it. Especially in light of Bond brutally killing Killifer by feeding him to a shark.

I however, do think that M is a dickhead in regards to not being patient and reasonable with what Bond has to say to him. M pretty much brushes off the fact that Felix was brutally attacked because in M's words, "He knew the risks!" In other words, M was basically telling Bond that he knew what he signed up for. That is to me, an extremely callous and small-minded thing to say.

It would be like telling the family of a firefighter or police officer or solider who was killed in the of duty, to not be upset over their deaths, because they should've known that there was a possibility that they would die. And again, M is extremely dismissive when Bond reminds him that Felix's innocent wife was gang raped as well as brutally killed on her wedding day no less.

Also, why doesn't M seem to care or pay any mind when Bond tells him that the Americans won't do anything about Franz Sanchez? Bond didn't clarify by saying that the American authorities in Florida can't pursue him as long as he's out of their jurisdiction. I get that M doesn't run a vigilante operation, and it wouldn't be the best idea for his agents to go after on the British Secret Service's time, money, and resources, anybody who personally pisses them off.

But still, M takes this blunt, "it's my way or the highway" approach when dealing with Bond. He seems to view and treat one of his top agents as little more than a commodity than as a human being with actual feelings.
