Parshat Raeh

I am really busy at work right now, and don't have time to write a proper post, but there is a Rashi at the end of Shlishi of this week's Parsha that is bothering me, and I wanted to write it down.

If anyone has any thoughts on this Rashi, Please leave me a comment.

Pasuk 12:28 says:

כח שְׁמֹר וְשָׁמַעְתָּ, אֵת כָּל-הַדְּבָרִים הָאֵלֶּה, אֲשֶׁר אָנֹכִי, מְצַוֶּךָּ: לְמַעַן יִיטַב לְךָ וּלְבָנֶיךָ אַחֲרֶיךָ, עַד-עוֹלָם--כִּי תַעֲשֶׂה הַטּוֹב וְהַיָּשָׁר, בְּעֵינֵי יְהוָה אֱלֹהֶיךָ.

Guard and listen to all these things that I command you so that it should be good for you and your children after you for ever, for you should do the good and the straight in the eyes of HaShem your G-d
(my translation).

Rashi says:
"Hatov" (good), means in the eyes of Heaven
"Hayashar" (straight) means in the eyes of people

Leaving aside questions of reward and punishment (which the pasuk relates to directly), my question is why is it important that our actions are not only Right (in the eyes of Heaven), but that they are seen to be right.

Surely there are cases where the right thing to do will be critisized or rejceted by society.
If an action is Right, but not embraced by society - does that make it any less right?

I wanted to follow this up in other sources, but I am travelling right now and don't have easy access to sforim.
If anyone has any insights, please leave me a comment.

Shabbat Shalom
