I'd join Team Rocket for a bit for the experience and further training of my Pokes but I'd resign and go out on my own eventually.
If you've read the manga at all, you get the feeling that Team Rocket isn't just something you 'resign' from, due to how evil they are. Lol.
This, but with Team Magma. Setting up Pokemon Reserves to protect rare pokemon from capture, studying volcanology, fighting forest fires. Seems nice. And -personal preference- I like their outfit better than Aqua's. I'm not really an evil sort of person, so if it was an evil team, I don't think I would be able to join.I'd join Team Aqua... but after the events of RSE. Mainly because I think that after the near-destruction of the region, Aqua and Magma reformed and became people working for the protection of the environment rather than eco-terrorists.
Although I wonder how, theoretically, people were supposed to join teams such as Team Rocket? >.> Was there some sort of screening process to find only those who were truly 'bad' enough and to keep out undercover agents from infiltrating its ranks? /overthinkingit
