What's bothersome about letting God make these decisions without our input?
In practice, it is much more bothersome to request such an input than to make these decisions without requesting feedback, but the purpose is partly to gauge the reaction of potential Opposition and to encroach the territory of known enemies simply by postulating theories which they are likely to resent.
To put your ideas in writing is an obvious war of words, which is the same as spiritual and psychological warfare.
In spiritual warfare, words (John 1:1 & Revelation 19:13) are often used to attack the enemy without necessarily naming Who is the actual enemy, because they know Who they are and they can sense your attack is directed against them, both on a spiritual and psychological front.
On the one hand, God still has the option to make these decisions without your input, but on the other hand Jesus is still a human who has the same limitations as any other human.
By nature, humans will psychologically require the approval, cooperation, and encouragement of their social peer group, which is why Hitler tried to surround himself with sympathetic supporters of his cause, regardless of the fact that the rest of Europe was probably hostile towards his Weltanschuung.
Consequently, the Hero of Armageddon will still prevail, although the rest of the world are probably against such a policy of genocide.
Due to his small group of loyal supporters this Central figure of the new covenant will ultimately prevail against the rest of the world who are mostly against it (Psalm 47:2-3 & Daniel 2:44, 7:14 & 27).
