Should I feel guilty about playing a certain champion?

This is actually my first post on these boards and I wasn't sure where to put this...so miscellaneous it is. (tried general discussion, but my summoner level on the boards is 11 atm????)

NOW. What I mean by the title is do you think a player should acknowledge or feel guilty that the champion they are playing is easy to play? That getting fed/making plays on that champion means nothing because they are easy to play.

Now, I play a lot of Diana and the reason I bring this up is because I was playing a few games on my alt account and ended up getting fed. In one of the games the enemy had a jungle Vayne and told me to uninstall from my lack of skill (I laughed) and in another game the same thing pretty much happened. I went 16/1 and there was a duo that was trash talking me about how none of my kills even matter because my champ is easy to play...they were playing Garen and Annie...I found myself thinking the same thing "it's not like Garen and Annie are hard to play."

THAT BEING SAID. No, I don't personally think Diana is that hard to play, but I love playing her and have tons of fun playing her. Oddly enough I find myself having an easier time playing other champions like Ahri, Liss, or even Zed and Yas. (I'm not saying these guys are the easiest champs to play, but I find them to be more forgiving or safe in a way). Should I eeeeeven feel guilty when I feel I could be having an easier time doing this by playing Ahri or pretty much any other midlaner with mobility in their kit?

I think any champion has the potential to make plays and outplay their opponents, but it's true that some champs have more mechanics to manage then others. How do you guys feel about this? Do you ever feel even a little guilty for playing a certain champ? I admit sometimes I feel bad for killing ADCs as quickly as Diana can do....but it's still fun.
