I like Eridan too much so I was like ‘what if I just made a post about it’.
And by that I also mean intense character analysis kind of. Let’s see where this goes.
But yeah, ERIDAN! I think one of the main moments I liked him at the start was that despite being this huge dickhole, he would keep on having this moments where he would be a genuinely nice person or you would just see some horrid emotional issues! And it just made me get…really attached to him!
The thing about Eridan is that he gets a lot of his self-confidence from other people! His self-esteem is at it’s best when other’s respect him. At the first pesterlog with Feferi, he’s pretty cordial and the main emotional problems he’s having are actually due to a loss of respect from someone! Eridan claims to be genocidal but he doesn’t have the balls to kill everything - just to kill enough to gain people’s attention and respect.
When the attempted angel genocide ended up not getting respect or affection from anyone (on the contrary, it made him look like an idiot), he started trying more direct routes. He started using pathetic routes to fill quadrants, because if someone wants to fill a quadrant with you, it means they like you enough and that you’re considered worth something in their eyes. Except he just got rejected, woops!
It can be concluded that he might’ve eventually joined Jack to feel like he was winning for once, or so that others would fear/respect him, or maybe to gain the respect of Jack himself.
The other thing I always liked about Eridan is that he always has these small moments of honest not-dickheadedness in the middle of his dickheadedness! He could’ve been a good person if he was raised up differently!
But Eridan was raised with the idea that he was better than everyone due to blood! And he started finding every reason to support that idea that he was better! And soon he just had this paradigm of all the lowbloods, and even if he did like some of them, he would find some excuse to show that they weren’t friends even if they were!
And basically, when it comes to the point where the hemospectrum isn’t supported anymore, he still had this view of all lowbloods as inferior, and he pushes it around everywhere, and then he gets confused why nobody likes him because of it because on Alternia he at least got some respect based on the fact of his blood.
And the lack of people’s affection towards him (in Eridan’s view) eventually makes him go out to prove himself or find something better with leads him to join Jack.
I might type more later when I’m not so lazy.
