Recruiting Another Fraternity's Pledge

[Moral Dilemma]

So there was this Freshman guy (let's call him "Nick") who I started becoming very close friends with last semester. He was very accomplished in High School, and he is incredibly driven to be successful in college. Great GPA, well-dressed and groomed, and a gentlemen with the ladies. He introduced me to his less-impressive, but still very nice roommate and childhood friend (let's call him "Will"), and I decided to actively Recruit both of them for Spring Recruitment.

After establishing a good relationship with these guys and inviting them to hang out with the Fraternity, they started asking about joining. I explained everything to them, and I started introducing them to Brothers, "This is ________ and __________ they're interested in pledging next semester." I thought I had it in the bag.

Now, I was always much closer with Nick than I was with Will. I considered Will to be my friend, but I just didn't have as good of a relationship with him. After one of the SG meetings, I start talking to Nick about the Recruitment events, and he tells me that he's not sure if he's pledging my Fraternity after all.

Will was planning on pledging a different Fraternity, and Nick was worried that if he joined mine, it would hurt their friendship. Furthermore, he kind of liked the Fraternity that Will was interested in, and could see himself joining.

He asked me what I thought about all of it, and I told him (perhaps not accurate advice, but it was how I felt, and it is still how I feel) "If you two end up joining a different Fraternity, you will probably be friendly with him, but you probably won't be his best friend, at least while you are both in college" I tried to qualify it any way I could with the "college is a place to make new friends" and "Maybe we could try and convince Will to still pledge [my fraternity]?". I could tell he was still torn about the whole situation, and he promised that he would come out to all of our Rush events with Will if he could, but I knew that my "sure things" were not guaranteed any more.

In the end, Will pledged a different Fraternity, and (very reluctantly) Nick went with him. I really had my heart set on this guy, but I can't blame him for making his decision.

Then a couple of days ago, Will and I see each other on-campus, and he asks if we can talk. He says he's having second-thoughts about the Fraternity he pledged. He starts telling me about how he doesn't think he fits in, he doesn't think the guys in the Fraternity are very nice, and he really doesn't like his "pledge name" that he got because he's Asian. He tells me that he picked this Fraternity because he thought they were the "Frattiest" and they threw the best parties, but now realizes that he may have made a mistake. He wasn't completely set on dropping out right there and then, but he asked if there was any way he could still accept his bid to my Fraternity.

I know if Will ends up quitting, Nick will almost-definitely follow. It's not against any Recruitment rule to depledge one Fraternity to join another, and it's (oddly) not against any rule to actively Recruit someone from another Fraternity, but I know I would feel shitty doing it. If the tables were turned, I would feel terrible if someone stole two of the pledges from my Chapter, especially if my Chapter was struggling for membership in the same way theirs is right now.

I don't know what to do in this situation. What do you guys think? Is it really wrong to pursue someone who's pledging another Fraternity, even if he might not be happy with it?
