I disagree. It is true that sometimes Jealousy can take the better of us and that sometimes it can cause us to do things different than how we normally do or feel certain emotions that we wouldn’t normally feel. However the scale upon which we feel these new emotions and do these new actions varies depending on how jealous we get. if jealousy continues to build and build and build overtime then it will eventually lead two irrational acting however simply getting jealous of someone over a small menial thing does not make a person completely irrational period it also depends on what that person is getting jealous over. just because someone gets jealous about one thing one time doesn’t mean that they’re completely irrational person for the rest of their life. it may just be whenever they encounter that one other thing they remember the experience. however if what they’re going jealous over is a really important thing to them then they could become irrational.
