yeh but retaining a village is not fun! ur defense perform at 50%, so they could easily just take the villages right back and little you could do short of throwing away alot of troops!The church rule means that if there village is outside of your church radius you can still attack with 100% as long as your attack village is inside your church radius. So even if they are outside of your radius you should still be able to take them.
Moral is a problem i can see, but they are crap so they probably dont biuld troops. Im sure they should present no problem to you.
