HELL NO. We draw a line as to what corporate behavior is permissible and dissolve corporations that cross the line. What you're asking is if we need corporations just this side of "too shitty to live." Nope.com.
Although I agree with the sentiment, I do wonder at which point does the medicine become worse than the disease? That is not to say that I don't think that some of Amazon's practices shouldn't be curtailed, but for every effort made, something is lost.

That being said, I'm not sure that shark is the proper term, or at least, I don't think the shark is the worst enemy. The leach is the worst. It's one thing to watch companies beat up on each other using their own resources, but when they are using the public's resources to fight each other, that's when it's really bad. Wallmart is a big leach. Amazon will make the transformation, but it's not as far along yet.
