Well, it's revealed in Wind Waker that he originally just wanted to take over Hyrule because he wanted better living conditions for his people or something, which is actually really interesting and makes him a far more interesting character. Mind you, that's pretty much been retconned because I guess that made him too complex and we can't have that, now can we?

There's also the timeline where Ganondorf kills Link and triggers the Imprisoning War. The surviving soldiers of the Royal Family rally behind the Sages and seal Ganon away with staggering casualties, which leads to Link to the Past, Link Between Worlds, then Zelda I & II.
You're forgetting the Oracle games and Link's Awakening, but I guess that's okay, because apparently Nintendo has as well, hence why they were massively retconned. But I guess you're right, Ganondorf is horribly evil if you consider that; if his actions lead to the existence of A Link Between Worlds, that makes him one hell of an evil bastard.

...umm.

UMM.
There are a ton of horribly evil Nintendo villains, many of whom are way worse than Ridley.
- Dark Samus/Metroid Prime infected multiple planets with Phazon, decimating the populations of local life forms and horribly mutating the survivors, driving many of them mad. It also caused the deaths of three of Samus' closest friends/allies.
- Hades from Kid Icarus Uprising started a massive war and then harvested the souls of those killed in the conflict.
- Pious Augustus from Eternal Darkness murders countless innocents over the course of two thousand years in an effort to summon a malevolent elder god.
- Ashnard from Fire Emblem: Path of Radiance starts a huge war and enslaves Rajaion, the prince of Goldoa.
- Majora's Mask caused the deaths of two revered heroes (and it's implied that it killed the Deku Butler's son), paralyzes an innocent old woman and leaves her in the Woods of Mystery to die, convinces a band of pirates to steal a Zora woman's eggs, turns a man into a child just a few days before his wedding, resurrects the population of Ikana so that they can suffer in undeath, calls down the moon to destroy Termina, and gets the Skull Kid blamed for all of this.
That's just to point out a few. I'd mention the villain of Xenoblade Chronicles, but that would get into major spoiler territory.
