The Yidden felt like Hashem took them out of Mitzrayim only to kill them, and the Seforno explains that they were afraid since they had worshipped idols in Mitzrayim. But is that not a good reason for a person to suspect that Hashem is super-angry at him, and is planning to kill him? After all, an Oved Avoda Zara is Chayav Missa. So why were they wrong when they were scared and cried in a way that Chazal describe as: םָנִח לֶשׁ הָיִכְבּ baseless without merit?
One thing is for sure: Don’t run after Fruma negatives! They could be a total Yetzer Hara. “But I sinned and Hashem is punishing me for good reason!” Beware! (On the other hand, maybe your Cha’rata (regret) and pain about your sin does wonders for you! Every case is different.) Be very, very careful not to fall into the “frum” trap of “I deserve this punishment and I know why I’m getting it!”
I had a bad case of Roiz (cellulitis), Rachmana Litzlan, which keeps me in bed normally at least 2-3 weeks! I immediately discredited all my sins as the reason for the Roiz. I started defending myself and being Dan myself L'kaf Zechus, and the Roiz disappeared in two days, with Hashem’s help. Remember, there is a major Yetzer Hara to feel guilty and wrong and being punished.
But being Osek in Teshuva in a light, happy way is the most Geshmake experience, and it should always be done. The more serious, the better; as long as it’s Geshmak and B'simcha. But blaming your issues on your sins is predominately a total Yetzer Hara, no matter how much it looks like that’s the reason (unless you have a positive doable Tachlis with your blaming).
Perhaps this is the secret of his success. And the Rambam says that anyone can become a Moshe! It depends how you look at yourself!
