Do they weary Hashem?
Radak: This is an anthropomorphism, like Leshon Bnei Adam. Hashem "Lo Yi'af v'Lo Yiga" (Yeshayah 40:28).
Malbim: You attributed weariness to Hashem, as if He tires and cannot oversee deeds to pay man according to his actions.
Why does it say "Hogatem Hashem b'Divreichem"?
Malbim: After rebuking them for their evil deeds, he rebukes them for their evil thoughts of heresy.
Why do they say "u'Vahem Hashem Chafetz"?
Rashi: You see the Resha'im succeeding, and the Tzadikim are afflicted and stumble. You say in your hearts one of these two ways. (a) Whoever does evil, it is good in His eyes - therefore, He makes him succeed. (b) Refer to 2:17:4:1.
Malbim: Either (a) [What we call] evil is not evil - it is good in His eyes, or (b) If it is evil, He desires evil.
Why do they say "Aye Elokei ha'Mishpat"?
Rashi: If not [that Hashem is pleased with evil], where is Elokei ha'Mishpat? There is no judgment or judge to take payment [from Resha'im]!
Malbim: You bring a proof from serenity of Resha'im and afflictions of Tzadikim that there is no Hashgachah or judgment.
