How is Hugo Baskerville evil?

As the legend tells, he trapped a woman in his house, and then chased her when she escaped; he was in turn chased by a demonic hound that ripped his throat out and then haunted his descendants.

“Know then that in the time of the Great Rebellion (the history of which by the learned Lord Clarendon I most earnestly commend to your attention) this Manor of Baskerville was held by Hugo of that name, nor can it be gainsaid that he was a most wild, profane, and godless man."
