No one steals delegates. They vote their convictions.
The primary season is not an election. That's why we have such a hodge podge of state level processes to select a nominee. Open primaries, closed primaries, caucuses etc. If a state level Republican or Democrat party decided to flip a coin, it would be their rules (I believe this actually happened in the Democrat primary.
So, what happens with all the delegates that went to Carson and the others? No one can tell them they have to vote for Trump or Cruz. I don't even think Carson or the others have the authority to give their delegates to another person. They may be bound to vote for the original candidate, but after the first ballot, its up for grabs.
We had a President selected by a plurality (Clinton), and where did that get us. Let's hope that after it is all over, we can unite behind the nominee and defeat the Democrat nominee.
Freebies, promises or schmoozing to get a delegate to flip is disgusting. I feel that way now and I would feel the same way if they were given a ride on Trump Force 1 and a relaxing stay at Mar-A-Lago. It may be legal but it certainly isn’t ethical. It stinks to high heaven.
