Luke and Anakin are different, remember. You really can't compare them. Luke is selfless and would never use the Force to gain power. Luke also had a somewhat safe childhood with Owen and Beru. The only real problem was that they wouldn't let him leave. Anakin always wanted to control things, even as a kid ("I don't want things to change!"). He was a slave with ambitions - even his best friends made fun of him because they didn't believe in him. I think it's more than likely that Anakin had quite a bit of anger inside that he unwittingly let out as a Force power. He was finally gonna prove his worth when Sebulba nearly got him killed. I'd get frustrated, that's for sure! I still personally think it could work.
