Why do you think people choose to use poisons when they wish to harm someone? what characteristics of poisons make them a choice for some murderers?

Its because Murders tend to be mental and they want their victims to suffer. So they choose poisn which can have some very painful effects if consumed or such. It would kill the victim but it would be a very painful death which is what the murders intentions where by choosing posin as their tool of killing.

the reason some people sacrifice their own life for another person's life could be that they are in love with them and would do anything to keep them safe a protected even if that means risking their life in the process

glitch or non-saved account.
