Remember that Shadowrun is a game about penetrating security systems, The most lucrative shadowruns target the rich and the corporate, and these people know there are metal psychopaths like this out there. If the goal is to break into places, rather than compare who has the biggest gun, then this type of character becomes a liability to the team.
It sounds like you just want to have fun with it though. Just remember not to crush the rest of the team in the crossfire if that's the case.
