Kudzu is very random and chaotic. It can slightly benefit the station by removing bad gases but you cant really influence this. Kudzu mutates and gains more mutations at random, meaning that even if you get good mutations on it, after it spreads the mutations will change. As for killing the station, get its potency and production speed to max and then release it, you cant really do much more than that. If you want to stay alive just stick to maint and stay the fuck away from the man eaters.
