Sometimes I'm a little puzzled by other Disney fans calling Gaston evil and talking about how monstrous he was inside.
Gaston and Prince Adam/Beast, as I'm sure many of you have noticed, bear many similarities: they are both shallow and self-centered and sometimes violent and even cruel, the Beast moreso than Gaston. The fact that the Beast is seemingly more evil than Gaston is understandable of course-Beast has had to live in isolation for years, and I'm sure Gaston would've behaved just as badly in Beast's place
However, in my opinion Gaston's biggest flaw was his ignorance. He was unable to understand Belle's dislike of him, and due to his confusion and embarrassment over her rejection he became determined to make her his wife, thus tried to blackmail her. I'm not defending Gaston's eventually deplorable actions, and I'm not criticising Belle, but Gaston's unintelligence, coupled with his self-obsession, led to his choice to blackmail Belle and thus try and kill the Beast.
But his unintelligence was probably due to upbringing, and I believe that his self-obsession came into being because of the sycophants like LeFou that surrounded Gaston.
In the fanfic 'Picture This' (http://www.fanfiction.net/s/2831327/1/Picture_This
), Gaston tries to seduce Belle and eventually the latter falls in love with him. It keeps the characters' personalities, including Gaston's flaws, but shows that Gaston is not evil-he's simply ignorant.
In conclusion, I believe that Gaston is a misunderstood anti-villain, and deep down he's just as attractive on the inside as he is on the outside.
