Did Nikola Tesla believe in morality?

Well, considering he was often the victim of scams 'invented' by J.P. Morgan and Edison, it seems he was the type of person who would rather trust a person than not.

Because he was not given what he was promised for his work, he spent a lot of time digging ditches to survive. Just a glimpse into his character, but a quote to support his morality would solidify it.
