Is this unethical?

CO ($27.20)

Hero ($23.95)
BB ($25.00)
UTG ($10.45)
MP ($48.70)

Preflop: Hero is SB with T[img]/images/graemlins/spade.gif[/img], T[img]/images/graemlins/heart.gif[/img].
<font color="#666666">1 folds</font>, MP calls $0.25, <font color="#CC3333">CO raises to $0.75</font>, Button calls $0.75, <font color="#CC3333">Hero raises to $5.90</font>, <font color="#666666">2 folds</font>, CO calls $5.25, <font color="#666666">1 folds</font>.

Flop: ($13.25) K[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets $5.00</font>,

(Any comments on that bet?)

<font color="#CC3333">CO raises all-in ($21.20)</font>, <font color="#CC3333">Hero raises all-in ($12.95)</font>.

At this point I ask Villain via chatbox "will you show if I fold?"... and he answers "YEAH"

So I call.

Turn: ($52.40) 8[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players, 2 all-in)</font>

River: ($52.40) J[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players, 2 all-in)</font>

Final Pot: $52.40.

Villain shows 9 9
