Tough call.
This is honestly one of those questions where there's no "right" answer, but I'll try to give you one or two anyway.
First off, not to sound pessimistic, but whatever a particular person's "baggage" is, if you don't think you can handle it, chances are you're right
(and in a case like that, you probably wind up hurting both of you if you try)
But let's say you've met someone and you're already heavily attracted to them, but they've been hiding their "baggage" (no surprise, most people will) and now - after already committing your emotions to this person - you find out about it.
This is the point where you have to be strong,
and wise. And honestly, the first thought that runs through your head when you find out will be telling.
If your first thought is "oh Lord, how awful; I want to comfort you", then you've got a shot at being strong enough to handle it.
If your first thought is "whoa, how is this going to affect me", then - not to be critical - but chances are you're not ready for this.
One thing to keep in mind if you
do choose to have a relationship with someone who's been victimized in the past: Some people - and sad to say women especially seem prone to this - have emotional attachments to the one that hurt them that can be
extremely difficult to overcome. Be aware that you might treat your significant other like a king or a queen, only to ultimately have them dump you for that person that made them feel like scum. They may even justify it by saying that "God is leading them" back to that person.
I know it doesn't make sense, but trust me, it happens a lot, so be prepared
