The 3bet is almost certainly not a bluff and as such villains range after 3betting a UTG open is probably something like {QQ+,AK}

By 4betting, we are giving our villain a chance to play QQ and AK correctly (that is, by folding) and a chance to play AA correctly (by shoving - since you're calling every time). We're not forcing him to make any kind of mistake.
