To Swear on one's life is a verbal promise or oath made by the speaker, inteded to dispell doubt from the intended audience. It is effectively an offer to the recipients to take the life of the speaker if they are, in fact, lying, and so is taken to be an oath of truth and sincerity.
However, despite this, it is still used to mislead, as the "promise" is non-contractual: it does not actually permit the audience to justly take the life of the speaker if they transpire to be lying.
The swear word is a euphemism for excrement.
If by "Swar" you mean swear, then he does it because it's who he is. I mean there are people who swear and some that don't :)
cack? Do you mean cake? Why would cake be a swear word?
An old way to say "I promise" is "I swear by my honor" or "I swear on my life."

It means stupid and is also considered a big swear in spanish-speaking places. Just like 'bloody' is a swear in England, 'stupid' is a swear in Spain.
