Computer Science or Engineering if I want to work in Social Work eventually?

I want to do a double major, the first discipline would be Philosophy. I am trying to decide between CS and Engineering for the second major. I like abstract more, so if asked about personal interest it would definitely be CS. But I have no desire to work in tech company and all. I want to travel and do social work, help out people in third world countries and all. I’m really interested in working for the UN. What would be a better choice for me, CS or Engineering?

Why do you want either for such a career? What is the end goal?
