Because the germs from the raw food contaminates with the germs from the cokked food. Even when on the chopping board they should never be kept together.
You should defrost it in a refrigerator, if possible. If you boil it when it's still frozen, you risk having a rubbery lobster. If you boil it, keep it in the shell and plunge into boiling water for just a couple of minutes. If you broil it, crack it after defrosting and remove the lobster meat. Broil it for just a couple of minutes to get color. Since it's already cooked, you just want to make it "fresh" by heating very quickly. Cooked lobster tail will curl and shrink if you re-heat it too long. You can also serve it cold after defrosting. With pre-cooked lobster, this would probably be your best bet.
Every cook uses a chopping board. ( or should )

A sharp blade should be used for chopping chicken.
Red boards for red meat. Brown boards for cooked meat. Yellow boards for poultry. Many restaurants use color coded chopping boards to avoid cross contamination. Certain colored boards are used for specific food items such as red meat, poultry, fruit and veggies. Red boards are typically used for red meat. Using different colored boards does no good if they are not washed regularly. ANY board whether wood or plastic, should be washed after every usage.

Only if it is then being cooked before eating, you can put in raw meat as long as it is being cooked with the rest of the lasagna afterwards, but make sure it is fully cooked before you eat it, red meats should be browned in colour with no traces of blood.
