A much better question would be, "Why does God send anyone to hell?"
Even if God is so petty as to subscribe to the "an eye for an eye" nonsense (unlikely since even us small, flawed Humans are capable of rising above that), no Human is capable of committing so heinous a crime to equate to eternal torture. I doubt any Human has the ability to even imagine a crime equivalent to that - much less carry it out.
It's not God sending someone to Hell. It's the person rejecting God. It's very simple to avoid actually.
