They don't have to use the word "excuse". What they're saying is that Sasuke is somehow a redeemable character, in terms of his goals and ideology, because he had a crummy childhood. That somehow, as one of them put it, because he didn't have anyone to talk to about his "feelings" after the clan was massacred, that makes his genocidal tendencies completely normal (it isn't) and understandable (its not).

Which is, by definition, an excuse.

And while yes, you're right, Sasuke seems to have stopped wanting to kill the entire village (doesn't redeem the fact that he fully intended to before this arc began), he still, as pointed out by TheUltimate, wants to kill Naruto.

So... there's that.
