== == You have to break this all of the way down to cells. When a cell takes in seawater, it also takes in salt. Salt will dehydrate the cell so if the cells dehydrate, you dehydrate. == == You may think you are rehydrating when you drink salt water but you're not. The kidneys can only make urine that is less salty than salt water. Therefore, to get rid of all the excess salt taken in by drinking salt water, you have to urinate more water than you drank, so you die of dehydration. Here is the complicated reason. It is because of hypertonic solution. Hypertonic solution means that outside of the cell is saltier than inside the cell. Water moves out of the cell to create equilibrium (a contition in which the concentration of a substance is equal throughout a space) and then the cell shrinks. This makes your blood diluted which in the end is bad.

No, Salt water doesn't directly kill people. If you swim in salt water, it cannot kill you. If you drink some salt water you'll be fine. However, if you ONLY drink salt water it can kill you, because your body will use more water than it gains to try to flush the excess salt out of your system.
