You kill something when you stop it from being alive. When a person kills another person on purpose, it is called murder.
Killing might also mean stopping something from happening, for example "lack of money killed his plans to go to Europe".
You kindle a fire when you first start it. The word kindle can also be used to describe something else starting, for example "a love for her was kindled in him".
