Yes, Killian was a small part of the group that destroyed Hades. Said group consisting of Zelena, Emma, Regina, Arthur, and Killian. Robin was, unfortunately, collateral damage, as he was not seeking Hades destruction, just trying to rescue his daughter.

Because Emma and Killian passed the True Love test, Killian at that point should have been able to been revived (though I will say that from a story perspective I actually liked that he was still in the UW for this episode). So from an overall perspective, he had earned the privelege of living, but got screwed over big time by Hades.

The revelation of the Olympian Crystal as the means to kill Hades was unknown to anyone until Arthur and Killian found the pages. From that point, Killian managed to magically get the pages to Emma. Emma saw the method of defeat and went straight for the Mayors office (slightly headstrong move on her part, but that's Emma for ya). At the Mayor's office, Zelena stops Emma outside where she gets the pages and also learns the truth of the crystal. I don't know if Regina ever got the message on the Crystal (things happened rather quickly once Zelena was back with Hades), but it doesn't matter. Zelena knew when she plunged the crystal into Hades beating heart.

As for rewards, Killian was not the only one rewarded, he just happens to have gotten a really good one. Emma is also rewarded by having Killian return. Arthur actually may be rewarded once he overthrows Cruella and is allowed to rule the UW as it was meant to be ruled. That just leaves Zelena and Regina, who BOTH lost true loves (Robin's sacrifice to save Regina I think qualifies that relationship to the True Love status).

Time will tell if Regina is ever able to overcome fate and actually get to hold on to her happiness for more than a month.
