OOOh, you got me back on this one.

This is a toughie too!
I would say that overall, breaking the law to help the friend in need is worse, because you could always search out ways to do things legally, but it is sort of case sensitive. I mean, if it's something like helping someone cover up a murder or extort money or something, then no.
Keeping your feelings to yourself?
OR
Expressing them albeit being very vulnerable?
