Justifying pages and posts text. Is it a good idea? (And how to do it properly)

[floatingpurr]

Hello, I'm wondering if it could be a good idea justifying text in blog's pages and posts. I haven't seen any quick option to to this, apart from wrapping all the markdown in something like

<div style="text-align: justify">
# This is your markdown

Lorem _ipsum_ foo bar baz...
</div>
