Euthanasia is a big and complicated word that means helping someone die if they are very sick and in a lot of pain. It's like being very sick and having a big owie that can't be fixed, and not wanting to be alive anymore because of all the pain. Some people believe that it should be allowed for doctors to help those people end their life peacefully and without any more pain.
Now, this is where things get tricky. Some countries like Canada and the Netherlands have decided that euthanasia can be a legal option for people in certain situations, such as if they are terminally ill or suffering greatly. Other countries, like the United States, don't allow doctors to help end someone's life. This is because there are many ethical and moral questions around whether it's right to end someone's life early, even if they are suffering.
It's important to remember that the decision to end someone's life is not one to be taken lightly, and there are many safeguards in place in countries where it is legal. Doctors and medical professionals carefully consider each case, and the decision to proceed with euthanasia is not made lightly.
