And both sides have a point when Jaina begins to imprison or attack innocent civilians. One side is pretty much explained in the Horde's Purge of Dalaran. Rommath basically says that every Sunreaver they manage to get out safely from Dalaran, is another Sunreaver that swaps his loyalties to the Horde. Lor'themar also says it...due to the Alliance (in this case Jaina, and to a lesser extent, Vereesa and her Silver Covenant) they are being pushed closer to Hellscream's Horde - to think he had thoughts about LEAVING the Horde for the Alliance, which Miss Peace-Lover fucked up big time.
However, while saved civilians and stronger/more important individuals can become good additions to the Horde - some were part of Dalaran's Kirin Tor to be at peace. One of the Magistrix' you save on the Horde side pretty much says "So I'm being kicked out of my home? ...Wow, kbye." and Arcanist Savor: "So long, Dalaran.." So both sides have a good side, but also a downside. There is no perfect choice in this if you want to prevent another betrayal.
Now, for the atrocities the Alliance performed...those aren't that many compared to the Horde of old and new. Most of those happened during the First and Second Wars, during which the Horde were bloodthirsty, demon-worshipping Orcs. My Alliance lore isn't perfect but...let's see.
Medivh bringing the Horde into Azeroth (Medivh had two personalities, a friendly one - part of the Alliance, and a dark one due to Sargeras)
Imprisoning the Horde in Internment Camps (This one isn't really an atrocity, considering it's a lot better than butchering them all...)
=> Follows up with Durnholde's prisoners being used for amusement as gladiators (This one can be considered an atrocity, yes)
The Culling of Stratholme (Arthas was Alliance-alligned, so this can be considered an atrocity as well - unless you want an atrocity against the Horde...)
Garithos ordering an execution on all Blood Elves for treason he caused himself with his racism - which would've succeeded were it not for Vashj. Dalaran's prisons were anti-magic.
Camp Taurajo, explained multiple times...most of those soldiers were convicts, and since the Alliance had so many costs...criminals becoming soldiers was one option among others. Still, shit went down.
Now...Horde has a far longer list, and I'm not going to name them all but...since we like digging in the past.
Butchering the Draenei.
Bloodlust so bad they even killed their own in rage.
Using the bodies of the fallen Humans to create Death Knights.
Sacrificing Humans for their 'demon masters'
Warsong attacks on Ashenvale (post WC3) - continues in Cataclysm.
The events of Stonetalon Mountain - granted, the Overlord misunderstood his orders but still an atrocity in the Horde's name.
Attacks on Hillsbrad Fields, and with Cataclysm - Southshore as well.
Attacks on the Kirin Tor outside of Dalaran's protective dome - followed up with attacks on a shielded village in Silverpine (Cataclysm)
Gilneas invasion.
I could go on, really... so yes, the Horde does a lot worse and a lot more recently. Garrosh does a lot of bad things, but he also did do some good things. Sadly, the bad overshadows the good. And while I don't agree with his methods for Theramore - he had every right to attack it, same for North Watch. I don't recall those soldiers ever being neutral...and Theramore was supporting the Alliance by letting them move their troops through to the Barrens.
Conclusion: Both sides have done bad things, either more or worse - or the other way around.
