A very well written piece. Except for one tiny problem. The last time El Matador, appeared in a Marvel Comic,

he had given up crime, and was so pathetic that the Scourge who had been sent to kill him gave him a pass.

(This was in Captain America, I don't remember which issue. At the time there were multiple killers called

Scourge around, not just the one that is currently in Thunderbolts.)
