well, dieng is bad, and might be painfull, but antifreeze is reasonably fast. if i was killed, i'd probably die thinking something about how my family and friends would deal, hoping that they'd live on. i don't believe in an afterlife, so i only see one loss for the person that dies, anything it might have done, but that's uncertain to say the least, and perhaos the pain he suffers in the process. the once that live on will have to deal with missing the dead, which is very, very hard IMO.
sonehow, i find it harder to deal with the death of somehow i never liked all that mcuh, then with the death of someone i loved a lot. the last is bad, i feel very bad, but you know how to deal with it. with the former, your feelings get in your way a lot more.
