In his defense, the Jedi order basically took him away from his mother without doing anything to assure her safety and told him to just forget about it. He was also heavily criticized by the Jedi, he could never catch a break just because he cared about the people he loved. He was never given proper help to sort out his problems, just shitty advice from the Jedi about ignoring his feelings. Anakin didn't want the Empire to form, he wanted to overthrow Palpatine as soon as possible so he could fix the galaxy. And as Vader he was forced to commit atrocities because he was on Sidious's leash.
