What is Judith Jarvis Thomson's perspective on the trolley problem and how does she propose to address the ethical dilemma presented in this scenario?

Judith Jarvis Thomson believes that in the trolley problem, it is morally permissible to divert the trolley to save more lives, even if it means sacrificing one life. She proposes the "doctrine of double effect," which allows for harm to be caused as a side effect of a morally good action, as long as the intention is not to cause harm. This approach helps address the ethical dilemma by balancing the value of saving more lives with the moral implications of causing harm.
