friends in disguise

I have been in a similar situation. I had a friend who hated another person who we both are also friends with. The fight they both had had nothing to do with me until my friend told me to hate the other person. Suddenly I am caught in a situation where I had to choose between both my friends I had been friends with for along time. Long story short, I ended up staying friends with both of them. So to answer your question, I would say NO. Do NOT hate the friend who is also a friend of a person you hate most. Just because they are friends of the person you hate most, how does that make them your enemy? They haven't done anything to you. They happen to be just friends with the person you hate most. Don't ever burn bridges. When it comes to talking to the friend who is also a friend of the person you hate most,just be normal and just ignore the fact that your friend is friends with the person you hate. Just forget about and treat him as your friend. Yes...of course SOMETIMES...in rare cases you might have to watch what you say because your friend might tell your enemy. Don't lie either. Just be honest but be aware in rare cases. Other than that...just be normal and stay their friend. Don't let your enemy hinder your friendship with others. If people started hating their friends because they are friends with your enemy...they are not going to have a lot of friends. A lot of people have enemies. And people know people. Your enemy will have people..who know people...who know people..So it's a connection. Ok this rant is too long haha...But you know what I mean right? Just stay friends. Don't hate.

Hi. I have a lot of friends who are also friends of my enemies. I try to maintain objectivity on these relationships but I become more careful/cautious of my words, actions and dealings with them. There are few of them whom I was able to maintain good relationships despite the fact that they are friends of my enemies.

My opinion, you have to hate this person who was you close friend and betrayed you in the end.
