Which is just icing on the cake. S1 Picard tells us Icheb was allowed to join Starfleet, S2 tells us Borg can't... or was it just Seven?
If fans pushed this point, we'd get a "Icheb is a man, so he has privilege that Seven doesn't" or some bullshit like that.
We all know the truth: It's shitty writing. Seven is le sad face cause she can't be badass captain of Starfleet, so Picard gives her the Stargazer at the end of S2, however that's supposed to work, given that by commandeering that ship, the only reaction of the crew would be to call Security and have her put in an arrest cell. And rightfully so.
I bet whatever braindead moron fans this show actually has will go "It's like when Chewbacca finally got his medal!"
I guess the best way to approach Q is to imagine him as a guy with an ant-farm.
Sure, he might take interest in an individual ant and do things to help or troll it, just to amuse himself, but ultimately, it's just an ant, so it will die eventually die and Q might mourn the loss of that ant for a moment, but there are many more ants and they live so short lives in a tiny world you can't even begin to comprehend. So yeah, no way you can really get attached. Every couple dozen generations or so, Q is bored so he picks another ant.
From his perspective, humans and their human problems are just the pointless meanderings of ants. Even all of humanity is barely worth his attention, cause they have been around for a blink of an eye as far as he's concerned and never reach Q levels, so they are ants, stuck in a galaxy-sized ant-farm while Qs can go dick around in an entire universe.
Millions of humans die to Borg, it's like we hear about one tribe of ants destroying another tribe of ants. We go "well, sucks to be them, now let's see how these new ants shake things up" and we move on.
If you want to give Q a more serious spin, you could dive into Q's history. I would think it might match his personality to have made terrible experiences interacting with species in the past when he got invested in their fate and tried to help, just to realize that anything he does is in vain, everything is chaos, even when he helps them survive one situation, they might die a million years later to something else (which still is just the blink of an eye to Q) and that he constantly has to decide if he gets involved and helping them or if he lets things happen naturally and they might die. Ultimately, he stops getting invested in the meanderings of lesser beings and merely does it for his own entertainment.
I dunno, there is potential here I think. Potential, I might add, without making Q a dour borefest.
"Sir, the full report and assessment of Admiral Janeway's actions in the Delta Quadrant has been finished... the high volume of personal logs and ship data made this a very time consuming work, but here's the result."
-"Ah yes. Let's find out how Janeway fared in the Delta Quadrant and how well she upheld our rules and morals... Oh no. ... OH NO."
