Wait what? The main antagonists (not sure if you can really call them villains tough) do die in Gundam Wing (or at least one of them), even though it's probably the Gundam series with the smallest body-count except for the ones were the Gundams are digitalized toys who fight in cyber space.

Either way I would strongly advice you to watch the other Gundam series, since Wing is one of the weakest members of the franchise.

And in Sailor Moon the vast majority of villains is killed. There's actually a whole lot of death and blood, but only in the manga. They pulled some manga-to-anime censoring acts that make the already infuriating censoring of Fairy Tail pale in comparison. The anime is more of a re-write which only loosly connects with the manga than an actual adaption of the source material.

As for Aquarius: Don't be so sure about that. She might have gone after the ship and only accidentally (or not) swept Lucy along and only later claimed she was aiming for Lucy due to her quirky personality. Later in the anime we get a few signs that Aquarius actually does care for Lucy in spite of her words.
