Greed can lead to stealing for more, which can lead to murder for a financial gain from a will
Pride can lead to starving yourself to look beautiful
Lust can lead to rape, which can lead to you murder your victim
Envy is when you want someone not to have somthing you're jealous of, so you take it away from them. That can mean, say you are jealous of someone's girlfriend, you might kill the girlfriend.
Sloth is when you can either be too lazy to get up, so your bones may become unusable, and because you'd probably to lazy to have any friend's you might actually starve from no food/nutrition or you might kidnap/hire someone, like a housekeeper then treat them like a slave, ending up killing them (that has actually happened)
Wrath is just basically when you want to cause so much harm, usually if somthing bad has happened, say your child was murdered, you found out and you were face - to - face with the murderer, you'd just lash out and kill them. This can also get you killed if they're with friends who might of might not be armed, or you get taken to court and sentenced to death
Gluttony is usually associated with eating too much food whilst others are starving, you can also die if you become too fat and...explode, or more like just block up your arteries.
So it does lead to sin, greed leads to murder, pride to starving yourself, lust to rape and kill the victim, envy to kill someone, sloth to weakening bones, wrath to murder, gluttony to exploding
