Flowey did not have the same goal. Flowey just wanted to play with the multiverse over and over. He helped people at first but then just got bored and decided to kill everyone. Also Flowey is tragic and when he becomes Asriel, all he wants to do is reset everything to start over before the incidents with Chara happened. Chara right off the bat wants to destroy humanity and, once they get the opportunity, destroys the entire world of the game. Chara is by far the most evil character in Undertale.
