Spinel's breakdown

Intro The reason I made this is because I will make anything that comes to my mind to be honest. (These characters are from Steven Universe) Spinel and Steven get into a fight and Steven is focused on trying to change Spinel into a good person. But Spinel says "When you change, you change for the better. But when i change.....I CHANGE FOR THE WORSE!" Spinel believes that she will always be evil and cannot change to be a good person. But Steven dosen't give up on her like everyone else would. (I haven't watcehd Steven Universe but i know enough from videos that i have seen on youtube)
