Which contradicts the writing which 'tells' us that Magnussen is such a bad villain, but doesn't 'show' us.
'Show not tell'.
When it comes to Magnussen's blackmail victims how do we know whether they were bad people who deserved to die or not? How do we know that Mary doesn't deserve to die due to these terrible acts she has apparently perpetrated?
It might depend on from what moral vantage point one might view a situation, as perhaps Magnussen's decisions could be defended by the same moral criteria which apparently supports Sherlock's moral justification to murder him.
We don't know. There's little to say that Magnussen was as bad as was made out other than what we were only told to think. Someone being shown licking and flicking faces isn't enough.
Didn't we actually see Sherlock commit an act which was morally worse than anything we'd seen Magnussen do?
Licking somebody's face is very unpleasant, I agree, but then again I suppose so is blowing somebody's brains out with a gun.
I think that you need more than saying that an action is somehow morally virtuous just because Sherlock carried it out.”
We've crossed swords before on that subject (or should i say we've crossed typing fingers).

So i will try one last time to make you understand...
my position
If we believe Magnussen that there were people standing by to prevent Watson to die, there are problems with that as a defence.
In court, and of course there are different formulation in different jurisdiction, but weither it's attempted murder or actions which threatens the life of a person, the fact that you had people standing by to help won't prevent you from being accused of something. Even if they do act and prevent the death, it is at least torture.
Second, in a public and lively place around a bonfire, there's a multitude of things that can not go according to plan. Which would result in a murder. If Magnussen is absolutely not a murderer like you seem to think, why do something as risky as this. Of course, there's no way to know if the then murder would be linked to Magnussen but why risk your blackmailling operations on people hired to do something that you can't completely control. (rescuing in a unpredictable surroundings).
Third, we only have Magnussen's word that there were people standing by to prevent Watson dying. I don't give him much credibility in the truth department: first, in a detective story, for me, every vialin is a liar, until proven otherwise. And we know Magnussen can lie, the whole mystery on how to prevent him doing wrong is based on a lie; the famous vault everyone think exists but doesn't.
If there were people standing by, where were they? Sherlock arrived barely in time to save Watson. Were they waiting until Watson started to burn? Had something gone wrong and they were late? Or do they simply don't exist?
Those last questions all point to something outside the world of blackmailling. And if Magnussen did that to Watson, it's probable, during all the years he operated, he did it to others. Don't know that but probable.
One other thing we don't know but is probable.
He threatens Mary to give her secret away to people who would kill her. As long as he doesn't do it, that's in the realm of blackmailling. But again, it is highly probable that, at some point in his long career as a blackmailler, someone will have said piss-off to him. If he doesn't carry his threat, he loses credibility so he will have done it. That's just probability but logical, imo.
Anyway, in my mind, the first points about Watson in the fire is enough to say 'he's not just a businessman and blackmailler. He plays with people life, not just reputation.
Even if some of his victims deserve to die (can't believe all of them who have threats on their life deserve it), it's taking the law in your own hands, which is still criminal and not the actions of a simple businessman.
Another point you make about Sherlock; i never wrote it's ok to shoot someone because it's Sherlock doing it. I might think it was the less worst thing to do in the circumstances but it still makes Sherlock a murderer. You say there's no difference if Magnussen calls ennemies of a person which would result in a death. The difference is Sherlock just kills him; Magnussen uses that fact to treat people like s..t before having them killed if they don't comply. For me, it's a big difference.
He's bad because of that.
He's bad because of, at minimum, torturing Watson (attempted murder from the arguments i gave)
He's bad because he blackmails.
He's bad because he treats his victims like animals (even when there's no possible killing involved), which is not the actions of a simple businessman.
I think he's a complete vilain and you think you could go bowling with him if he didn't have pressure points on you.
I don't think we'll convince each other but it makes us explore different angles of an important aspect of series 3, which is good enough to make me happy
