“EVERYTHING Hashem does is for the good rather YOU/WE like it or not and approve it or not.”
This is a fact that all of us as yidden know, so we never have a right to question Hashem on anything going on in the world currently or already in the past rather it looks great or vice versa a tragic jersey city terrorist act.
Everything Hashem does is for the good 24/7 and any person who disagrees with Hashem has a lack of faith and need to work on him/herself and bring themselves back closer to Hashem. Perhaps make yourself a daily learning seder of Chovos Halevavos (duties of the heart) and bring yourself closer to Hashem
