Were Yisrael more righteous when the Beis Hamikdash was standing?

(24,5) How goodly are your tents, Yaakov, your dwellings, Yisrael!

Behold, in this posuk the Jewish nation is one time referred to as Yaakov, and another time as Yisrael. Also, the Beis Hamikdash is one time referred to as a tent, and another time as a dwelling.

But we find in the gemara that when Yisrael do the will of Hashem they are called Yisrael, and when they do not obey Hashem's will they are called Yaakov. And it says in the Midrash that when the Beis Hamikdash was standing it was called a tent, and when it was destroyed it was called a משכן which means a dwelling, but which also means a collateral, because the Beis Hamikdash was taken as collateral when it was twice destroyed for Yisrael's sins, as Rashi writes in the beginning of parshas Pekudei. The Midrash also teaches that as long as the Beis Hamikdash was standing the generation were called wicked, but when it was destroyed they became Tzadikkim.

Thus Bilaam was saying to Yisrael "How goodly are your tents, Yaakov" - when the Beis Hamikdash is called a tent, that is, when it is standing, it is good, but on the other hand they are called Yaakov because they are wicked; "your dwellings, Yisrael" - but when the Beis Hamikdash is destroyed and called by a name which means collateral you are called Yisrael, because then do the will of Hashem and are thus Tzaddikim.
