Mest is the only one to actually have a plan to stop August. The others are just scared shitless by his title and magic power, even considering the fight lost beforehand.

That negotiation had zero chance of success, absolutely zero.

Besides, had he been stabbed through the heart, he could've died there and then. This series has rather strange establishments of endurance and generally it seems that magic power equals endurance, but there was still Makarov's heart acting up during the Fighting Festival and he was the strongest mage of FT, but he was still not immune to heart problems.

There was also Brandish being knocked out by Cana's punch, so certain physical attacks bypass a difference in magical powers. So stabbing an old man may very well be a far more effective attempt to kill him than throwing some flames, lightning or other pure magical attack at him.

Besides, pulling off his plan right in front of August is proof of keeping his cool and staying collected.
