I have always hated Charlie as a character. He is much less likable than any Klingon or Romulan that appeared in the original series, and even villains of the week like Khan, Apollo, Roger Korby, Kodos and Flint were more sympathetic.
Charlie behaved like a spoiled brat whose powers allowed him to act on impulse with terrible consequences. His whole life he developed no impulse control and no empathy whatsoever for others simply because he hadn't needed to because of his isolation.
In more familiar terms imagine an indulged youth with the means and privilege to do whatever he pleased and without any consideration for others.
It's not surprising he would be a hard character to sympathize or identify with.
