Merlin should be the one that value life above all things like he did in the first three seasons.

Not the whole three seasons. He sacrificed Nimueh and tripped Mordred up so the soldiers could catch and kill him when he was about ten years old. He released Kilgharrah despite seeing a premonition of him attacking and hearing him refuse to swear that he would not attack, so the resulting deaths are on him.
