You don't really need to overthink it because the most important point of this series is, that the mc is a villain:D his morality is already dark, not even grey anymore XD that's why I don't really care about what's happen to the others, bcs ofc their lives are going to get fucked over by mc as long as they're the object of his revenge. And just like you said, this is also fiction so I'm just enjoying the journey no matter how fucked up it is(´ڡ`)
Its simply because of the point of view. If the mc were the girls, most would root for them too
Although I do agree that there's a pattern of girls and women being the "bad guy" here. Before it was the girls, now its the prince's mother
Everytime i read this, i feel bad for the girls. Its not like they were irredeemable people, heck they could even be considered good but after reading the comments i realise there are a lot of ppl who dont give a shit abt morals as long as they are the main character or someone beautiful. Then again, maybe its just cus this is fiction and i am overthinking as i usually do
