[Doctor Who] Did the 4th Doctor give Davros the idea that the Daleks could suppress the universe rather than just just the planet Skaro itself?

He did yes, he told him of the entire future of the Daleks. How they would conquer and kill billions.  Before the Doctor's interference Davros believed it impossible that there even was life on other planets. 

I guess you can blame the Time lords overall. They sent in the one man who they knew wouldn't have the will to do what needed to be done, without any weapons or backup, it's little wonder the Doctor messed things up. It's lucky he even got out alive, hardly anyone else did.

If the TL's wanted the Daleks stopped a quick, simple execution of Davros BEFORE he created them was what was needed.  They bottled it as did the Doctor. End result, trillions dead, including ironically all of them eventually. 

What a mess up from the oldest civilization in history.
