Clutch Pedal Issue

I've had my Duster for some time now and I was wondering if this behavior of the clutch pedal is normal:

at the beginning it is very hard, then it eases up very suddenly, and then it is very easy to move, but on the return, the pedal hardens up instantly and violently which can precise clutch control very difficult. Especially when parking the car with the manual steering. I just want to know if this is something I should be worried about or something is not working normally. Any ideas, feedback or help as long as they don't criticize my sock choice.
Thanks to everyone in advance for the help.
