John 3:17

Οὐ γὰρ ἀπέστειλεν ὁ Θεὸς τὸν υἱὸν αὐτοῦ εἰς τὸν κόσμον ἵνα κρίνῃ τὸν κόσμον, ἀλλ᾽ ἵνα σωθῇ ὁ κόσμος δι᾽ αὐτοῦ.

Not to Create Separatists

For the God did not send away the Son into the Order in order to separate^70d the Order, but rather so that the Order might be saved straight through himself.

For God sent not his Son into the world that he judge the world; but that the world might be saved through him.

Not to Pick out and Separate

Greek κρίνω. Strongs #2919, krinó.

1. to separate, put asunder; to pick out, select, choose (Homer, Herodotus, Aeschylus, Sophocles, Xenophon, Plato, others; μετά νεανίσκων ἀρίστων κεκριμένων (chosen, picked), 2 Macc. 13:15; κεκρίμενοι ἄρχοντες, Josephus, Antiquities 11, 3, 10); hence,
2. to approve, esteem: ἡμέραν παῥ ἡμέραν, one day above another, i. e. to prefer (see παρά, III. 2 b.), Romans 14:5 (so τί πρό τίνος, Plato, Phil., p. 57 e.; τόν Ἀπολλῶ πρό Μαρσυου, rep. 3, p. 399{e}.); πᾶσαν ἡμέραν, to esteem every day, i. e. hold it sacred, ibid. 
3. to be of opinion, deem, think: ὀρθῶς ἔκρινας, thou hast decided (judged) correctly, Luke 7:43; followed by an infinitive Acts 15:19; followed by a direct question, 1 Corinthians 11:13; τοῦτο, ὅτι etc. to be of opinion etc. 2 Corinthians 5:14; followed by the accusative with an infinitive Acts 16:15; τινα or τί followed by a predicate accusative, κρίνειν τινα ἄξιον τίνος, to judge one (to be) worthy of a thing, Acts 13:46; ἄπιστον κρίνεται, Acts 26:8.

The primary meaning of this couldn't be more clear. He is not sent to pick out, approve, esteem, or separate people according to opinion, etc.
