To abort or not to abort

[Heywood]

Heywood, i'm going to introduce a scenario that I've used before:
You are holding in your right hand, a 3 month old baby.
In your left, you are holding a petri dish containing a human zygote.
You have to drop one of them.
Which one do you drop?

I ask you this because, as you say, these two both have potential for consciousness and life. So you shouldn't be able to choose. That may be the answer you give but I don't think its the answer you would think.
You would drop the zygote, like everybody else, because you realise there is a difference.

Why do I have to drop one?

If I can only save one, I save the 3 month old because I value the 3 month old more than I value the zygote.....but I do value both.
