Probably better to stick with this one, since new information has really changed the topic.
With Minus now part of canon, it seems it wouldn't have made too much of a difference. Maybe he wouldn't be as naive and have a pragmatic side similar to DBS Vegeta, but that's about it after having been turned into a Supermeng clone.
Ignoring Super and going by what the original manga presented though, he'd probably have been quite vicious and battle hungry by nature. However, I doubt it'd easily make him some Raditz clone. Human civilisation has been shown to change Saiyans with far closer ties to their heritage such as Vegeta, so Goku would've probably had some influence when interacting with them as long as he didn't go on an Oozaru rampage, given it would take a while before he reached Roshi's level (nevermind Kami). He'd most likely end up a lot like Vegeta's Cell Arc self or a less stupid version of Super Goku; selfish in his desire to fight stronger opponents, yet having the common sense to judge what's the best option in a situation. If following a similar trajectory to the main timeline, it'd probably mean he'd be killed by the Akkumite Beam.
