A ridiculous thought?

[the_main]

So I was playing a tournament, as I usually do. And there is a huge donk at the table, as there usually is. He's spewing chips calling down with bottom pair, and I'm hoping for a hand to bust him with.

About 20 hands in I raise his BB with JJ. He calls and we get 10 high, rainbow flop. He had me covered, but I doubled through him as he called my all in on the turn with a gutshot. This left him with 200 or so chips with a t50 BB.

Anyhow, he rebuilt his stack getting lucky until we both hand about 3k. Then, I get involved in another pot with him. I have TPTK and have him covered. He calls me all the way down to the river, leaving himself with only t400 behind.

So I think to myself - Why not let him keep these chips and hopefully he can build up again. He can possibly take out better players doing so, and also accumulate more chips which I can take. So I check and he checks behind, mucking bottom pair (he held 3-5off).

How ridiculous is my line of thinking here?

The actual result, if it means anything: Turns out he did indeed rebuild, catching some good cards and I took about 50% of his average stack before he busted for good.
