We don't actually see anyone negatively affected by Destroy either, except for seeing EDI at the end.

With Synthesis, the problem is a moral one - do you have the right to force this transformation upon the entire galaxy? Maybe it's the ultimate endpoint of organic and synthetic life, and maybe that's a good thing, but is it right for that change to be forced like this rather then developing on its own?

With Control, the problem is whether any one person should have that much power. Shepard may have the best of intentions, but as they say, power corrupts. We have a pretty fair idea what the last guy to want to control the Reapers would have done with them - is it right to give Shepard, or any other single person, the capability to do the same?

And both these endings have the problem of the Reapers continuing to exist in some form. The only ending that unquestionably ends the threat for good is Destroy.

For the record, I picked Control, but I do think that all endings have their pros and cons.
