Even though the amount of electrons that gets in the conductor is the same that goes out, when it carries a current of certain high amount, the net electrons flowing in the conductor will be more than the protons in it thus having a negative charge.

The net charge is zero,positive equals negative.

You're getting it wrong.Current being the movement of electric charges,the charges being moved are those already existing in the circuit.There wouldn't be any net charge in the conductor.

I just figured it out. Its because the electrons in a conductor also join the current(you put charges in one point and the same amount at initial, from the conductor leaves at the other poin) so, it will only get charged if the current(electrons) in the conductor is high, where the electrons become more than the protons in it. For that to happen large current needs to be passed through a small conductor. And i need to back that with an experiment.

whether you a pass a small or large amount of current to the conductor ;an equivalent amount of electrons will simultaneously exit at the other terminal/point,so the the conductor will always remain neutral.

the same amount leaving doesnt reduce the amount passing. (Current intensity is the amount of electrons that enter into a conductor at a time). E.g you pass large amount of water through an expandable narrow tube, though the same amount will leave as the one entering but, the total water in the tube at a time is large it will bulge the tube.

What you are saying is that accumulation of electrons can occur at some point in a circuit,this doesn't happen.If you remember,the electrons continuously drift to regions of higher potential i.e lesser electrons,so the charges simple can't accumulate this way.In principle,they act like they're all connected together so that any action at any point will simultaneously affect the overall flow,an analogy is that of the marble ball momentum transfer experiment in physics.That's why placing a resistor at any point along the conductor won't just impede the electron movement at that particular point but rather,the entire circuit.As for the expandable narrow tube example you gave,the expansion is due to the force it exerts perpendicularly on the walls of the tube.You may think the volume of water in the tube also increases,but the only way this is possible is if the rate of water outflow is less than rate of water inflow,the difference resulting in the extra volume which causes the bulge,the same perfectly applies to the electric circuit.
