Well, I think it makes Tyrion even more human, a bit like us. We find ourselves in dark places sometimes, Tyrion isn't immune to that. He is one of the most, if not the most, interesting character in the series, and I love what GRRM does with him.
Reading Tyrion 2 in ADWD, I am reminded of all the stages he has gone though, and how power is fragile. He was very powerful in ACOK, when he was acting hand, he was playing games with the likes of Varys, LF and Cersei. He was their equal (or he thought he was - that's open for debate), and showing quite a bit of cunning. However, he was showing his good side too, stopping Joffrey from hitting Sansa, thinking of schemes to protect KL from Stannis, working quite hard really.
Then it was all taken away from him, and he had a massive fall from grace. Disfigurement (nose), Tywin's return, forced marriage to Sansa (in which he shows some more humanity), humiliation by Joffrey (cupbearer), removal from the council, accusations of kinslaying and kingslaying combined, jail, ... wow!
Quite amazing really. I also don't begrudge him a little bitterness, even though he should count himself lucky to be alive and free(ish).
