I can think of one way for her to face consequences later on: there’s been no indication that her crimes are public knowledge yet. Maybe, if we’re lucky, something may come of that.

There was someone in one of the neighborhoods that I used to live in. I used to go to the person’s house and play video games or ride my bike with him around the area. However, he left and I wasn’t able to get anything like an email address or even a home address so that I could be able to maintain contact with him. In this case, is it particularly my fault that I wasn’t able to contact him or didn’t? If not, then you shouldn’t fault her for not being able to contact Sunburst or not trying to do so. Besides, Sunburst is the one who left.

Starlight believed that if she tried to make friends, then once they received their cutie marks, they would leave and not be her friend anymore. Why would she be motivated to even try if she believed that the outcome would be terrible? She was a filly during the time, so concluding that cutie marks would break friendships apart after seeing her friend sent to Canterlot right after he received her cutie mark would seem to be reasonable to her. Also, what makes you think that making friends is easy for everyone? I have never been able to make friends even the slightest bit easily, much less retain them. Besides, it isn’t like you can just replace friends.

Sunset stated that she planned to take over Equestria with the power of the Element of Magic. It’s likely that she would have tried to do so regardless of whether the element of magic warped her demeanor, so she didn’t have any other reason for the things that she did besides the pursuit of power.

Starlight was momentarily consumed by her anger after the four who chased her caused her to drop the Mane Six’s cutie marks. She lied only about the fact that she didn’t remove her cutie mark, but she was being sincere about her ideology. You just stated that she was beginning to lose her temper in the other occurence so she wasn’t exactly lucid.

Sunset was ordered to repair the destroyed portion of Canterlot High because she destroyed it, and the reason for the other students not trusting her afterwards is due to the fact that she had been continuously malicious to them before she saw the error of her ways. In contrast, the ponies in her village were mainly upset about Starlight lying to them about her cutie mark and also because she didn’t give them the chance to be friends without needing to have their cutie marks removed. The scope of Starlight’s actions were smaller than Sunset’s. Starlight’s actions affected only the villagers in her town and the Mane Six and as I just stated, they were upset that she lied to them. It’s not likely for the usage of the brainwashing room to be frequent if her villagers were convinced to follow her ideology and willingly had their cutie marks removed. In any case, she might have thought that the brainwashing room would be necessary.

Stating that she made the village because she believed that society wronged her and not because of her ideology is very misleading.

Starlight was angry when she attacked her followers, not corrupted or possessed. It was a conscious decision on her part to hurt others and being angry is no excuse for attempted murder/assault.
Starlights philosophy sprung from het belief that cutie marks were responsible for her pain and hated the current society for valuing them, hence why she wanted to replace it with her own. Starlight had no problem resorting to kidnapping and brainwashing ponies that were already happy with their lives and refused to buy into her philosophy and the fact that the other villiagers had to sneak around and have secret meetings for fear of reprisal does not pain a picture of a pleasent, altruistic supreme leader.

Sunset was cruel to the students at Canterlot high and she was rightfully ostrasized by them for it and should have had to do manual labor whether she blew up that wall or not. Starlight should have got the same and no amount of “good intentions” should have got starlight off as easily as they did.

Twilight forgave starlight because she is a good person and thats why we love her and forgiveness was both the moral and the practical choice on her part but redemption should be a journey filled with self reflection and discovery and should be earned in blood (not literally),sweat and tears untill you have proven yourself through actions. We got to follow sunset on this journey and the audience themselves was able to forgive her. Starlight on the other had her journey wrap up in a two minute montage and didnt do anything but screw around with the mane 6 and then was accepted back by the ponies she hurt the most the second she showed up with a sad look on her face.

I hope that season 6 does not open with the assumption that starlight has nothing left to prove because having starlight continue to flip karma the bird and carry on like nothing happened is a good way to make people dislike her more. In the end art is subjective and you have every right to like starlight but there are plenty of reasons for people to dislike her and her redemption should have been handled better then it was.
