Wrong again. There needs to be an element of "malice aforethought" to distinguish between murder and accidental manslaughter. So yes, it implies more than just one's death - it implies intent on the killer's part.

Oh, but you would be freely allowing the murderer to murder you.

Agreed.
If you live in a society that would easily trample on a person's rights, then your own rights are that much less secure. Standing up for someone else's rights makes your own more secure and ensures future support should they be at risk.
Giving to charity may result in emotional gratification of satisfying your empathetic instincts, better reputation in the society, people owing you one and tax breaks. So, rationality says, there is something in it for you.
