Why is this move bad?

Why did computer say Nd5 is a bad move??  I did it to force the Q back, then trade the pieces.  Tricky spot for opponent.  As played, opponent blundered.

While Nd5 threatens the queen and a fork on the king and rook, black can just simply play Qd8 and white misplaces his knight. It's better to trade first (Bxd4->Bxd4->Nxd4->exd4), creating doubled isolated pawns, then you gain the pawn by playing Nb5 which threatens a fork and the pawn. This is a better outcome than the awkward move you made.

Thanks for the replies.  I want to get better and this helped.
