Yes, power may seem limitless. But remember the tower of Babel? When humans thought they could build a monument to the skies, one that could reach the heavens. It was a symbol of their cockyness, they thought they had the power to match God's. But they didn't. God stripped it away from them and they fell.
Remember Samson? The strongest man alive, able to decimate armies. He died.
Same with Achilles, that horrible, monstrous Greek soldier. Killed by a mere arrow to the heel.
You say that "you can use power however you want and it will not turn on you". But let me give you an example:
In Indonesia, my country, we were oppressed by Western countries for so many years. The result? They were driven away, fought back. We feared them but also hated them. Those tyrants.
Another example is war. When you misuse that power to attack an innocent country, surely you would receive backlash.
Now, how do you defend yourself against this argument?
