Yes it is. He's scored 4 unopposed shots (no defenders) from 12 yards out to get to the tally he has, whereas Lukaku has worked for every goal he has scored this season.
No it isn't, if Lukaku isn't good enough to be the main penalty taker that is his problem. Anyway, you make it sound like all Kane does is score penalties.
Let's look at the stats
Kane 22 apps, 19 goals.
Lukaku 26 apps, 18 goals.
Even taking away Kane's 4 penalty goals, at his goals per game rate this season he would still score more than Lukaku.
Kane has 68 goals in 108 PL games. That smashes Lukaku's goal record by a distance.
