Existentialist ethics focuses a lot on individual choice. This means that people have the freedom to make their own decisions but also have to deal with the results of those choices. This freedom can be challenging and even scary. Here are some of the main issues people face when it comes to making choices from an existentialist point of view:

1. Anxiety and Decision-Making: Having the power to choose can create a lot of anxiety. People often feel heavy pressure from their decisions, knowing that what they choose defines who they are. This can lead to a kind of inaction, where someone feels so afraid of picking the wrong option that they don’t pick anything at all. Thinkers like Kierkegaard talk about the "leap of faith," which shows how hard it can be to commit when you're worried about regretting your choice later.

2. Absurdity and Meaninglessness: Existentialists believe that life doesn’t come with built-in meaning. Because of this, each person has to create their own values. This can be a tough realization since life's randomness and the fact that we all die can make us feel pointless. Camus talks about facing this absurdity without giving in to despair, but it's still really hard to find joy in life when everything seems so absurd.

3. Isolation: Each person is alone when making choices. This loneliness can make it tough to connect with others. Existentialist thinkers highlight that our choices are very personal, which can lead to misunderstandings and strain relationships. This isolation makes it hard to act ethically in a world that often relies on shared values and group responsibility.

4. Moral Relativism: Because existentialism suggests that everyone makes their own values, this can lead to moral relativism. This means there aren’t any universal rules or standards, so someone might justify any action just because they believe in it personally. This can weaken shared ethical beliefs, raising concerns that some people might excuse harmful actions without considering the larger moral picture.

Even with these challenges, existentialist ethics provides some ways to deal with the difficulties of making choices:

• Authenticity: Striving for authenticity can help people make choices that matter to them. By reflecting on who they really are and what they truly value, individuals can make decisions that align with their identities. This takes honesty about one’s motives and thoughtful self-reflection.

• Engagement with Others: Although existentialism stresses being alone, it also values connections with other people. Talking and engaging with others can give valuable insights and support when making decisions. Sharing ideas with different people can help someone understand their values better and lessen feelings of anxiety.

• Creating Meaning: Accepting that life doesn’t have built-in meaning can actually empower someone to create their own. By recognizing life’s absurdity, a person can find freedom in defining what is important and what gives their life purpose. This proactive way of thinking allows individuals to take control of their lives and decisions rather than feeling overwhelmed by despair.

In summary, individual choice is a big part of existentialist ethics, but it comes with many challenges, which can lead to anxiety, isolation, and confusing moral situations. Still, by pursuing authenticity, engaging meaningfully with others, and actively creating one’s values, people can work through these issues and build a fulfilling ethical framework that fits their unique lives.
