The expression in cold blood refers to homicide, or murder.
Specifically, it speaks to intent or premeditation. It didn't just
occur in the heat of an argument or by accident. It also hints to
the emotional view that blood and having a heart has an emotional
meaning. If you are "warm" blooded and "have a (nice) heart", you
would never commit murder.
