User blog comment:Legionwrex/Why Destroy is the worst ending (besides refusal)./@comment-4361160-20120709022231/@comment-2250460-20120709022804

You either didn't read the blog or didn't listen because it answers about half your questions.

Control is keeping the galaxy diverse, not screwing over future generations, and having Shepard survive (in a sense) along with the geth.

Destroy is selfishness at to the highest degree is you picked it just so that the Reapers are destroyed and Shepard lives.
