Thus I did not like the assassins at all because all of them seemed to be extremely unprofessional and frivolous to me. The entire gang looked like a bunch of people who accidently had gathered.
1. Did I use "frivolous" correctly?
2. Does the bold part make sense (it's a literal translation from my mother tongue).
Please, correct all my mistakes. I should know English perfectly and if you show me my mistakes I will achieve my dream a little bit faster. A lot of thanks.

Yeah, don't you hate frivolity in an assassin! Well, it depends what you think you're saying with "frivolous". It's not for us to say that they were something else, and that frivolity is not the characteristic that you are put off by.
"... who had accidentally gathered together."
