						Well I just noticed the small sample size OP gave (however, not in the original post).  If it's over a larger sample size, then I fold preflop, and am okay with it.  A 10/8 likely isn't 3betting an UTG raise from UTG+1 lightly.  He definitely isn't 3betting TT/JJ, and likely not QQ, and maybe not AK.  I doubt he will bluff in this spot, so that really leaves the two hands we don't want him to be 3betting with, AA/KK.   
 
Without reads, I would fold, as I don't like 4betting, because if he is bluffing he will fold those hands, and we would only be getting it in against the hands we are a dog too.  A call preflop would technically be +EV, based on our equity, and the pot odds we are being offered, since we have 40% equity against KK+, AK, and we must call $2 into a pot of what will be $6.35 so we only need ~31% equity to have  BE call.  However, this is overlooking how we are likely to get little value when we are ahead postflop, and can potentially lose quite a bit when behind (aka - being position raped). 
 
Eitherway, I don't think preflop is that bad.  I would likely fold, but I think a call is okay.  And depending on his 3betting range, a 4bet/call might be profitable as well (if he is 3betting hands like JJ/AK and intending to stack off).   
 
But postflop, I do not understand OPs logic in donking at all.  Let's assume villain's 3betting range is KK+, AK.  Donking this flop seems pretty terrible, as he will fold all worse hands (AK), and call all better hands (KK+).  The same goes with check/raising.  He will continue with KK+, and will fold out AK, which we beat.  However, if we check/call, we allow him to bet both hands that beat us, and hands we beat.  And we can easily check/fold Ace or King turns, while also giving him a chance to double barrel with AK on blank turns.
