The Caretaker’s array would have self-destructed if not for Voyager’s intervention. Therefore, destroying it minimized the impact of Voyager on the situation.
Since the Array was going to be destroyed by the Caretaker originally (or was supposed to), yes, that somewhat minimizes VOY's involvement.
Remember though that the self-destruct mechanism was damaged (which halted it) when the Kazon ship collided with the station (which was Chakotay's doing).
And, Janeway did say to the Kazon initially she intends on destroying the Array, to which he objected and started the fight.. Enter Chakotay, and his Maqui ship ramming action because neither VOY or the Maqui vessel had enough firepower to stop the Kazon battleship.
On top of that, Tuvok said it would be hours before he could access the mechanism to send them back to UFP space... and Kazon reinforcements were on the way.
So, in a way, it was Chakotay's fault for the self-destruct mechanism not working, but that WAS an unfortunate after effect of the battle that I don't think could have been predicted... plus, both ships might have been weakened still from their initial push to the DQ which damaged them originally (even with repairs, the crews might not have had enough time to bring the ships up to full strength).
Either way, the Caretaker wanted to destroy the Array... with the self-destruct mechanism out of action, Janeway simply finished what he started, thereby preventing the Kazon from getting their hands on a technology which in their hands could have resulted in reprecussions for that (or a larger) section of the galaxy (not just the Ocampa).
Janeway and Tuvok were on the station and managed to get a lot of sensor readings using the Tricorders... so they inadvertendly managed to scan the technology the Array had... I would say that's 'sort of sneaky', but most other species don't really whip out tricorders or scanners to familiarize themselves with their environment, so UFP was better prepared and stands to usually (if not inadvertendly) gain from that.
