But don’t you think Betty being with Jughead is also erasing her character development? She committed a crime for him, she’s someone completely different (and not a good someone) with him, she’s reckless and rebellious, this is not her at all. The reality is none of them are good for her both have problems and affect her in a bad way.

bughead:

except that it is her. she’s been making questionable decisions in the name of protecting the people she loves before her and jug even started dating. her relationship with jughead didn’t create her “dark” side. betty tortured chuck in the hot tub long before jughead joined the serpents. if you don’t blame polly or veronica for what she did to chuck, how can you blame jughead for her threatening cheryl or stripping? he had no idea she was going to do either of those things. i’d agree with you if jughead was encouraging that behavior, but he isn’t. he’s not hindering her development or destroying any progress she’s made. betty has behaved like that on and off since we first met her. it’s not something that started with jughead or is exclusive to him, and he’s not egging it on
