Die he, in my mind, lie under oath? Yes. His answers were intentionally evasive.
Will he be found guilty of perjury in a court? Probably not, because I doubt anyone has enough courage to charge him or carry through with anything, plus he was weasily enough he could probably skate on a technicality?
Is he toast? Who knows. Republicans have been lying and doing whatever the fuck they want for so long and never paid a price (and, in fact, been electorally rewarded) for so long that I doubt it.
But what is important is that his word is now shit, Republicans are on the defensive, we have more evidence of Republican wrongdoing re: Russia, and it will cripple the Republicans and have them on the defensive any time Sessions does something shady.
Other than that, he fits right in Trump’s swamp.
