IMO it's the best language for absolute beginners, if we are talking about classic Pascal without Borland extensions. It's very small language which could be taught in a few lessons yet it's powerful enough to learn classic data structures and algorithms.
The main drawback is that Pascal is not commercially successful, so you'll learn it and move on. Python, on the other side, is widely used, so Python knowledge is useful on its own.
Start from Pascal if you want to learn a lot of languages. I specifically would suggest to dive deep after Pascal and learn some assembly language, may be x86. They you'll have good basics and you can learn almost any language you want, C would be good, for example.
Main problem with Python IMO is that it's too high-level, it's dynamic, it uses GC. All those things are too far away from real machine code, so if you'll learn Python first, it might be hard to learn low-level programming and it's useful even if you're using JavaScript.
