The comparison to blood transfusion is really great and describes perfectly my personal feelings about the topic

• No forcing. No one can force you to give that blood transfusion to your sister. You can have million reasons why you don't or can't make that blood transfusion
• Your body, your choice. No laws that should change that
• Morally speaking, should you give that blood transfusion to your sister? Well, yes. Even if you hate her, it's still your sister and only you can save her (in this scenario). Especially when there's no life-threatening situation preventing you from blood transfusion
• Should you be punished for not giving your sister the blood transfusion? No. Will a lot of people think of you as an asshole for not saving your sister's life? Yes, unfortunately regardles of your reasoning
• Should we educate people about the blood transfusions, encourage them to regularly donate blood and help them to go through the process even if they're scared? Absolutely
