Common causes of meat spoilage are mold, bacteria and exposure to air. It is sometimes difficult to tell if a steak is spoiled or not, but if anything about the smell or appearance of a piece of meat makes you question whether or not it is still good, throw it away. Do not risk making yourself or your family sick.
I understand that the more done a steak gets, the less tender it will be. However, I've grilled some steaks to my perfect doneness that turned out deliciously tender. Unfortunately, it is more often a bit on the tough side - not usually *too* bad, but more chewy than I prefer. Obviously the cut, the cooking temperature, searing time, and the cooking times are all factors, as well as the starting temperature of the meat, dryness, resting time, etc.
