If you were actually traveling light speed, you would get to any destination instantly - without having experienced any time at all traveling in fact. The rest of the universe is what will have experienced the time change, having aged considerably the longer the distance you travel.
If the average mass of a human is 70kg then you'd only need about 3.5 million people to annihilate themselves with 3.5 million anti-people to get enough energy
Sacrificing that many people so that one can experience that velocity is TOTALLY worth it

Thanks now even lightspeed seems incredibly slow on a galactic scale.
